Just yesterday I had a duty queued and begun a match, only for the queue to pop after the first card was set, and there was no issue with me joining it on the spot.
If that is the case then it would only be not recommended if you aren't the job you queued as when you start a match. Personally though I'd rather play TT with NPCs when I'm not waiting for a queue myself, only because they have a card I need. Then again, I usually do nothing but wait when I'm in a long queue lol
