Default Getting tile adhesive off a plaster wall

I suspect the answer is no, but is there an easy (ish) way to get tile

Depends on the adhesive. Old adhesives are fairly water soluble,
sufficient that you can soften them with a wet sponge and scrape.

More modern adhesives are often somewhat water resistant (and these
won't soak off old tiles either, unless you use weak acid). These need
to be shifted mechanically. Tile setter's abrasive mesh is quite good,
but you need to make a wooden sanding block for it. Also a "brick
stone", a coarse abrasive block with teeth cut across its face. Your
problem here is that the plaster substrate is softer than the tile
adhesive.

Try soaking. Most tile adhesive is still usefully water soluble (it's
the grouts that are really waterproof).
