Unless it has been established for whatever reason that this is something the Maelstrom specifically allows for, then it seems unlikely. If a player wants to be able to do so specifically, that seems like a great time to write up a Custom Move of some kind, that they could purchase with an appropriate advance.
It does depend heavily on what the Maelstrom is like, though, for sure -- my experience with the game is that as the fiction of the Maelstrom gets more and more developed, it becomes easier for players to justify more esoteric or specialized uses of it even as part of a non-custom, Open Your Brain type move. E.g. if it has been established that the characters actually project their consciousness 'into' the maelstrom when opening their brains, then it becomes feasible that two PCs who have opened their brains at the same time might also communicate somehow while doing so -- because, in the fiction, that means they are both in the same 'place.'
But suggesting the same thing in the first or second session, before that in-depth fiction has been established, would seem like a kind of over-reach -- like Ebok says, it all depends on your group, but my own preference is to keep the Maelstrom simple and _specific_ to begin with, to help avoid turning it into a sort of swiss army knife of 'psychic stuff' that just kind of does whatever the players find convenient.
