Can the part you made from a computer slot cover be rotated out of the way? As the above poster asked can you push the catch in with your finger? If yes to either then the answer to your question is no. A better solution IMO would be something like that with bent edges that would fit around the boss so that rotation is impossible until the screw is backed out far enough. It should also be longer to cover the other part of the catch.
