Isn't there some kind of law against using a propane tank for
compressed air?

As long as a *new*, unused tank is employed this can be done.

I've done that myself in my shop - I found a *new* tank at the
local store that was never used, but being sold inexpensively.

The big problem is purging the methyl mercaptan stink out of them,
short of roasting the open tank in a bonfire which would make them
unusable for anything pressurized. Any ideas from you chemists out
there?

The standard way to get the petroleum smell out of a 55-gallon drum is
lots of steam, enough that the entire drum gets up to temperature. Bet
it'll work here too.
