in thread do $n exist in grep?

I got the sense that you didn't want just the captured parts. But if you only need the $1 from each match,

map { /^..(A|B)./ ? [ $_, $1 ] : () } @a

simplifies to

map { /^..(A|B)./ ? $1 : () } @a

but you could also go a step further and simply use

map /^..(A|B)./, @a

(I added this to the original post to show the options in one place.)
