Be brave and strip the wallpaper off. You may have to replaster the wall, but it'll give the tiles a good key. My partners place was plasterboard with cardboard in between, and having only tiled the wall, it's still going strong 13 years on.

Tom Mawson

In the end I bit the bullet and have started stripping one half of the paramount board off and installing some decent sized studs at 400mm centres to give the new plasterboard something strong to screw to and then used some grab adhesive and some smaller off cuts of wood to secure the existing plasterboard to the studs.
