You could replace orthogonal and immutable perhaps, but idempotency has a rather precise technical definition that doesn't really have any synonyms. It's a useful word too, because idempotency is generally a very desirable property to have in many systems. If you do any kind of system automation, it would get quite cumbersome if you had to keep talking about operations which only effect change when they actually need to.
