Short answer

Yes, in the true meaning of the word. "Muslim" is Arabic for one who submits to God (﷾). In the garden Jesus prayed, "not my will, but thine, be done". He fell on his face to pray, as Muslims do. He fasted, was circumcised, and kept the Law of Moses. He taught that God (﷾) is one and that God (﷾) alone is to be worshipped. The Qur'an says his disciples declared, "we are Muslims". It says Abraham too bowed his will to God (﷾). The Prophet Muhammad (ﷺ) said that the prophets are brothers whose deen (way of life) is one. This does not mean Jesus followed the law later given to Muhammad (ﷺ). It means he submitted to God (﷾). That submission is Islam, the whole way of life given to God (﷾).
