My guess is that it is more of a kennel cough right now and that yes, obvious a narrow trachea, but at that age probably not the trachea acting up, just the cough. You see, they are born with the narrow windpipe, it's anatomy that's a bit out of proportion. Usually their symptoms don't appear until they are older and fatter. Your puppy will probably clear up when the respirtory puppy thing goes away. It may come back to CT coughing at a different age. Like allergies can be harder on a CT dog. So can kennel cough. I bet many little dogs have undiagnosed CT because an xray hasn't ever been done. I'd give that pup a chance to clear up and I bet will be cough free for quite some time.
