Drywall is fine for a tile backer for this purpose. If you have extra lying around, better to use that than sending it to the landfill. Two reasons people might stay clear from drywall for a tile backer is moisture (not an issue here) and weight (a large wall of heavy tile could in theory pull the paper off the wall board, again not an issue here). Other options to consider is the cement board which is a PITA so say the least or a tile backer board which is much lighter and easier to work with. Also consider using OBS board as it's cheap and will offer a great surface for adhesive. If it was me I wouldn't bother with using messy mortar either, PL premium or a tile adhesive would be my choice.
