Use CHOMP wallpaper remover. Buy the concentrated formula but when mixing it with water add extra CHOMP. Then follow the directions on the bottle for wallpaper removal. Drywall that is not water rated cannot stand up to dampness or anything. That's why we paint or add wallpaper it actully protects the drywall besides looking nice. Unfortunately, without steam or wallpaper remover, the paper will not come off easily. If you use a putty knife, this can leave nasty holes in the wall. Either way you're looking at replacing what the last owners did not do right at all.
