Can someone reapply to be a Marine if they were discharged for not reporting mental counseling (per the recruiter's advice)?

I have a Grandson that joined the Marine Corp. When he joined he disclosed to the recruiter that he had had some court ordered mental counseling when he was younger due to an abusive Father. My Grandson never got in trouble, his Father did as he had also abused his daughter) The recruiter told him to NOT report it to anyone else, so my grandson didn't. While just two weeks away from graduating boot, he told his DI about the counseling. The DI then reported it to the higher ups. My Grandson was then discharged from the Corp for not reporting the counseling even though his discharge papers say "Due to no fault of his own, because he was just doing what the recruiter had told him". Can my Grandson reapply to be a Marine? He has never had any legal problems or behavior due to his Fathers abuse. He is 20 years old now and it has been two years since he was discharged. He Loves the Corps and still wants to be a part of it. Can a recruiter answer this question?
