No, and I will tell you why.
The reception of the profession of vows is a juridical act. In that case, even if the clergy were all laity, the laity don't know that. So if they make profession to someone they believe to have juridical power, like a bishop or an abbot, they commit an error of fact. In those cases the law of the Church itself supplies jurisdiction, so the profession of vows is valid and licit.
So in other words, if you don't know any better, the profession is real. Besides, it is a promise made to God.
