Canon 4 refers to, as you even quoted yourself, Sacraments in general. Ergo for that canon to prove desire for Baptism can replace Baptism, then Matrimony of Desire or Holy Orders of Desire must also be doctrines according to your twisted logic. So your canon cannot be proof for Baptism of Desire. All it proves is that SOME Sacraments can be received in desire, namely Reconciliation. Trent explains Reconciliation can be received in desire in other canons while also explicitly stating that the waters of Baptism cannot be metaphorical. Ergo, your canon does not prove Baptism of Desire and Trent does not support it in any way(and in fact refutes it, as BOD requires metaphorical water).

The answer is no.

This is explained by the Church in the quotes I provided.  To "enter into the kingdom of God" a man must "be born again of water and the Holy Ghost", which is the sacrament of Baptism.  Should the man be forestalled from receiving the sacrament of Baptism by an untimely death, as Saint Thomas Aquinas explained, "such a man can obtain salvation without being actually baptized, on account of his desire for Baptism," because "God, Whose power is not yet tied to visible sacraments, sanctifies man inwardly."

18. Is judged already: He that believeth in Christ with Faith which worketh by charity (as the Apostle speaketh) shall not be condemned at the later day nor at the hour of his death. But the Infidel, be he Jew, Pagan, or Heretic, is already (if he die in his incredulity) by his own profession and sentence condemned, and shall not come to judgement either particular or general, to be discussed according to his works of mercy done or omitted. In which sense St. Paul saith that the obstinate heretic is condemned by his own judgement, preventing in himself, of his own free will, the sentence both of Christ and of the Church.
