I have the Ehwaz rune. If I go into boss rush and take an item, can I use the rune to escape into the womb?
What if I had had "We Need To Go Deeper"?

Yes you can, with both the rune of Ehwaz and We Need to Go Deeper! The two items are fuctionally identical and they both work in the Boss Rush room. Keep in mind anyway that there is a not so low chance (~10%) of getting a Crawl Space instead of a passage to the next level when using these items.
A better way to be sure of getting out of the Boss Rush room is to use a teleporting item; this has also the added bonus of giving you a chance to get into the I AM ERROR room.
