If you are speaking of very old wallpaper that is in fact paper, you might get away with it.
The difficulty come with the adhesive used to put the wallpaper up... most of it is water based, which means when you saturate the paper the adhesive lets go, and the whole thing has the potential to bubble, wrinkle, or in some cases fall right off the wall.
If the paper is newer, it may be vinyl or vinyl coated, in which case the mud won't adhere well at all.
My best suggestion is to strip off the paper, before applying the mud.

Can you put sheetrock over tiles?
You cannot use sheetrock as flooring, period. If you meant on a wall, there is no reason you cannot put sheetrock over tiles. The question is why would you want to! Why not remove tiles and material behind, which is probably sheetrock, and then install new sheetrock. If it is an area prone to moisture you could use moisture resistant sheetrock. The job would look better and you would not lose the space by adding over existing material.
