I would think that the answer would be yes. Especially if the improvised weapon could fit into a scabbard like a sword sized piece of scrap metal or a broken table leg... but not a tree branch or a bar stool lol.
On the other hand, if you were creating the scabbard for a bar stool I don't see why it wouldn't apply. Roving the country with a bar stool on your back... always prepared for those taverns that have no available seats, to take a seat and catch your breath mid adventure or bash an enemy over the head with it because you excel at using improvised weapons lol.
