Is it ok to install tiles on gypsum plaster?

Several years ago, the kitchen was renovated: the walls were originally painted with oil paint. As much as I could cut down – cut down, then covered the remains of the paint with primer and put a plaster on top. After that, glued wallpaper.

Now decided to make an apron of tiles: what to do with the wall? Wallpaper neatly cut and bent, putty tried to scrape off as much as possible. Will it be enough? I really don't want to scrape off the old paint.
