This should not be possible, since you no longer have a second spot if you remove the Ranger. I think there are arguments to be made that it is possible, following the play Timing. However the designer thinks differenty, theme-wise it also wouldn't make sense I guess.
Reported from BGG: I placed a Ranger in the Dungeon's second spot, to reduce the cost of a Twig Barge and play it for free. This is the spectator link to the game: https://everdell.vercel.app/game/6yC4fetzaQExh84gbChgLU

As explained by James Wilson himself, this is not a legal move: https://boardgamegeek.com/thread/2031725/article/29624971#29...
