Can you deepstrike them with Denizens of the warp?
No reason I can see that you can't, so yes, you can. It's got the DAEMON faction keyword and so meets the requirements for the stratagem. You'll have to follow the rules when deploying it (as laid out in the stratagem) and once it hits the table it turns into a terrain piece.
