To obtain a wall kill you need to crouch up to a wall to lean up to it. You'll be able to strafe across the wall. From there you have to wait at a corner which you can peak around. From there you can whisper an enemy to come and walk past. While leaning against the wall and passing enemy you are given the same kill prompt. By killing the enemy whilst leaning against the wall you'll obtain a wall kill. Repeat 10 times. Can be done on any level.
