The Windows licence comes with the machine if it is already stuck on the case, in that case yes if you upgraded from that licence
If the Windows 7 sticker came with the machine / the disk that the previous OS you upgraded from, then I would imagine legally yes.
Selling it with the Windows 8 upgrade then you would also have to give them that too if you want to be 100% above board
