Not exactly the same situation, but LH had no trouble issuing my LX boarding pass at MUC for a ZRH connection this past October. So, unless there's an issue unique to either BD or whatever your point of departure is, it ought to work.

(Can't speak to the baggage issue directly since I had no checked bags, but interline baggage transfer has been around for a lot longer than *A, is near-universal, and tends to work as it should. When ZRH baggage handlers look at your bag they just care about the flight it's continuing on, not which alliance the airline operating that flight belongs to.)
