Answer: He can. There are many such cases in history. One such example is Baal HaSulam who surpassed his teacher from Pursov, a small town near Warsaw. When Baal HaSulam realized that there was nothing more he could receive from his teacher and that his teacher was in attainment of the Creator, he left and went to Israel.
I wish everyone to surpass their teacher and to keep advancing and that you will have students who will surpass you.
