Sexual abuse or playing doctor?

[tunatoon]

At age 15 y.o., son (child "A") reveals to mother that his stepbrother (child "B") touched him on his torso and private area both under and over clothes.  At the time of the touching, both boys were in 1st and 2nd grades or between 6 and 8 years of age.  He provides no further specifics about the incident, stating that he really doesn't remember much.

When B was 11 or 12 years old, he became a ward of the state after an incident in which he suddenly became angry with child A and threatened him with a steak knife.  Child "A" has never said that the two incidents were related; just that his stepbrother became a ward of the state because he has serious mental health issues.  B remains a ward of the state after repeatedly voicing homicidal ideations towards his father, stepmother, halfbrother (2 y.o.), and 2 stepbrothers (at that time ages 11 or 12 and 14 or 15).

Was the incident that A recently revealed an incident of playing doctor that young children go through or was it sexual abuse by child A against child B?

There is no way to know the answer you seek because only the two participants in the episode know the nature of it. With so mnay years having elapsed since the epiode, trying to reconstruct it now is pointless. If the boy you refer to as Child A is having any emotional difficulties now relative to the incident, he should see a therapist.
