No, I'm afraid it won't complete the quest if you slay Silver and Golden Knights on Bitterblack.

I just added this observation to the page when I recently forgot to slay them in the Pre-Game Everfall. In Post-Game the quest will not fail, but you can't complete it. The quest will simply linger on the quest list until you begin New Game Plus.
