Actually, I think a move action is any action that provides movement, in the same way that an attack action is any action that causes a figure to attack. It's the same reason why a minion reaver can't attack and skirmish in the same turn.
That is not correct, per RAW anyway.
Only a Move Action is a Move Action. Anything else that lets you move is just an ability that grants you MP (which may or may not require a Special Action to perform.) FFG has clarified, for example, that Immobilize only prevents a hero from using a Move Action or burning fatigue to gain MP. It does not prevent any other ability that grants MP.
Likewise, only an Attack Action is an Attack Action. Other abilities that allow the figure to "perform an attack" are not "Attack Actions." (A Monster Action that performs an attack will count as the monster's one attack for that turn, but this does not mean it's an Attack Action - it is still a Monster Action.) FFG has also clarified that OL cards, like Frenzy, which grant an extra Attack Action do not allow the monster to use a Monster Action that performs an attack. It only grants a "basic attack," if you will.
If you want to house rule otherwise at your table, I can't say I blame you. I've considered similar house rules myself, though I have yet to implement any. These would be house rules, though. They are not the official rules, nor are they "what the game designer intended." FFG has been fairly clear about their intent in this area.
