If your questions relate only to Stack Overflow, they should be on Meta Stack Overflow rather than here, though if they haven't been moved already, it's unlikely they were overtly limited to Stack Overflow.
That said, no, migrating them to Meta Stack Overflow will not earn you any reputation on Stack Overflow because participation on per-site metas does not impact your reputation on the site. It's only here on Meta Stack Exchange that reputation is awarded for votes on questions and answers.
Looking at your two undeleted questions other than this one, I don't think there's any reason to move them, though. They are applicable to the entire network, not only Stack Overflow.
