They can be used but don't neccessarily have the reach needed to remove tiles and can be slow. a tile lifter or scraper attachment (bit pricier if you can find them) for an SDS or SDS+ is a better idea.
The survival of the substrate depends on what it is. If its plasterboard then there is no realistic way of getting the tiles off the wall without destoying at least some of it. I've seen experienced guys get tiles off ply / ply backed tile backer board successfully but never manged it myself. Brick / plaster is relatively straight forward and even if you fuck it up is easy to reapir.
I saw someone use a multitool with some kind of scraper bit on YouTube yesterday and it whizzed through them and then again to clean up the adhesive. So I bought a multitool yesterday. Hoping it bloody works!
