Technically speaking OF COURSE they can tell - if they want to. You don't know what information it's sending, it could be gathering information about the source of the song as well.
Personally, I don't care - I have little totally illegal music (I copy music from CDs that I own), but even if not, I doubt Apple are against CD copies - after all, if they were they wouldn't allow you to do it in iTunes, would they?
It's the same as the cover album feature.
