Well, some believe the laws of logic are contingent and depending on God's command, too. Because they cannot accept God sharing space with something eternal and immutable, too, apparently. So, for such a God it would be indeed possible to move what is immovable. All He has to do is to suspend the contradiction by commanding that an object can have a property and not have that property at the same time.

The problem with this is that it's not possible and in fact, doesn't even communicate anything, and the explanation is lengthy, I'm trying to think of how to whittle this down since I'm trying to multitask with my thesis.
Basically there's a reason I keep using the word "utterance," because incoherent things are just utterances. Statements communicate: they have a reference (the speech about something) and a referent (the thing spoken about). Propositions are statements that have truth values: there is something about them that corresponds to reality. So for instance, "Green is the best color" is a statement because it communicates something, but it is not a proposition because it doesn't have a truth value (it's just a preference statement).
All propositions are statements, and all propositions are utterances (an utterance is just speech of some kind, whether it communicates or not).
All statements are utterances, but not all statements are propositions.
Not all utterances are propositions, and not all utterances are statements.
What it means for an utterance not to be a statement or a proposition is that it has no truth value and doesn't communicate anything: it has no referent that it's referring to (and therefore it doesn't even have a reference).
Logically incoherent things can't be referents because of their incoherence (in order to be a referent, logic has to apply: if A doesn't equal A, then what are you referring to when you say "A?" Nothing!) So utterances with logically incoherent combinations of words aren't referring to anything and don't communicate anything. It's important to realize that this is different than saying "this thing can't exist," it's stronger than that: it's that there is no "this thing" that's possible to exist at all. You might as well type "sduhghwlegewiy" instead of anything that's logically incoherent.
So when someone says something like "God can make the logically impossible possible," this is just an utterance. There is no referent, there is no reference, there is no truth value, there is no communication. It's equivalent to being "not even wrong." The person might as well have typed "sdghjkthjwutehitkewthweu."
Even God/omnipotent beings are bound by logical coherence because logic is really just limitation: what it means to be real or to exist is to be limited: limited to be a particular thing, and limited from being things that particular thing is not. That's what it means to exist at all. If you don't have that limitation, you don't have anything that exists: you don't have anything at all. Trying to even talk about it just produces an utterance.
