It has a clear plastic film over it, which will probably peel off, as mine did. The three colors and the "commodore" chickhead is bonded on and won't come off.
Unless he's
very lucky, I doubt he has a Commodore chickenhead on his 4000T.
However, I'd just go ahead and leave the A4000T sticker on, it seemed to be a plastic sticker and shouldn't be affected.
