There is a difference wether it's designed to be LWB from factory or if somebody takes a standard car, chops it in wto and then inserts middle bit to make stretch limo. Not to say that stretch limos(or factory LWB's) cannot tow but they are limited production run and small fraction of buyers would like to tow that cost of tests is too high. No tests done + no towing. It's the same with some medicines- they have not tested it for kids or for pregnant women so they will say not to be used for kids or pregnant women while it could be perfectly safe, they just don't have data because they never tested.
