I suspect tiles might pull off mortar without a lot of effort.

I think they used to use mortar in the old days - I had a splash back in
my kitchen so done. And they took some removing as the walls were also
skimmed in mortar, with a thin skin of plaster on top.

In the old days, I think it was done with sand/cement/lime render,
and then a very thin coat of cement, maybe pure with no sand, or just
with just a small amount of sand, to stick the tiles to the surface of
the render. (I was told, but it was a while ago and I might have mis-
remembered.)

Modern tile adhesive will be much easier to use though.
