I am not trying to argue the Discovery is suitable, but hopefully shedding some light on why it is stated.
My father-in-law owns an F150 and his model is not far off the towing capability of the Discovery. That surprised me.

If you read the warning from the Discovery owner's manual, it states, in part:
"The trailer hitch can malfunction and the trailer can break off from the vehicle." An "air suspension system making adjustments to stability" won't cause a steel trailer hitch receiver to "break off the vehicle chassis"...
But, believe what you want, after all, Land Rover only designed and manufactured the vehicle, what would they know ?????
