I do not think so, but the experts in here will know. They are talking about Hydrochloric acid mixed with hydrogen peroxide, not Sulfuric acid as far as I know.
Incidentally, drug store concentration peroxide is safe to handle, but the lab grade concentrated stuff is quite dangerous. It has so much oxygen available, that a spec of dust falling in the bottle of highly concentrated hydrogen peroxide can cause a violent reaction.
Also, I think you will find "Muriatic" is an old world term, and should be commonly understood there in the UK as well as here in the New World. Masons have used it since antiquity and it is used in many other trades.

But can battery acid be used as an etchant?
