The answer is yes.
Yes, there is a circuмstance and a doctrine which would not only allow but oblige someone to remove a name from the Canon.
The teaching is most wonderfully enshrined in the following historical episode,
Letter of the Holy Synod at Ephesus to Pope Celestine (full surrounding passage, Schaff/NPNF)
The Holy Synod which by the grace of God was assembled at Ephesus the Metropolis to the most holy and our fellow-minister Celestine, health in the Lord.
The zeal of your holiness for piety, and your care for the right faith, so grateful and highly pleasing to God the Saviour of us all, are worthy of all admiration. For it is your custom in such great matters to make trial of all things, and the confirmation of the Churches you have made your own care. For this cause we thought it well to notify your holiness concerning those things which were done in that Holy and Great Council. In the first place we enjoined Nestorius, as an innovator and as one who opposed the ancient ecclesiastical teaching, to be deposed from the episcopal dignity, and we anathematized him and his followers. We likewise bore witness against Theodore, and against all who support him. Moreover, those who had put his name in the diptychs, and who had been thus giving him commemoration in the Churches, we exhorted and rejoiced because they had removed his name and had ceased from communion with him. We therefore send you the acts and decrees (that you may know what has been done), and praying for your holy and apostolic seat we remain in Christ, your fellow-labourers and brethren in the episcopate.
Reply of Pope St. Celestine I,
To the most reverend bishops and clergy of Constantinople, health in the Lord.
We have received your letter and the information contained in it, and we rejoice with you that the truth of Christ has been defended. We hear that those who had placed the name of Nestorius in the diptychs, and so commemorated him in the churches, have removed his name and ceased from communion with him; for this we give thanks to God, and we praise your prudence and zeal in maintaining the faith. Continue therefore stedfastly in this course, taking heed that nothing be admitted which might unsettle the faith of the faithful, and preserve the unity of the Church which is pleasing to God.
Given at Rome, by Celestine, Bishop, servant of the servants of God.
The doctrine is that when one is morally certain that the one named in the Canon is a manifest, public heretic, their name is to be omitted based on the principle that Communion is only to be had among those who are one in faith and subordination to legitimate authority. To do otherwise - when so convicted - would be a sacrilgeous lie told to God and a scandalizing act of perversity by willingly expressing union with an enemy of Christ during the Holy Sacrifice. It would be a true violation of one's Catholic conscience.
This not only can be done before an official condemnation from the Pope, it is praiseworthy to do so, and using the same principles of moral reasoning that would allow +Lefebrve to consecrate bishops without the approval of Rome it would be NECESSARY for one who was truly convicted of the manifest, public heresy of these false prelates.
To claim otherwise, (when one is morally certain of their heresy) would be to deny the doctrine, impugn the saints, and disregard the approval of the Roman Pontiff.
