I don't think it is relevant where the clip took place or how it came about.

It is fairly logical and common sense to conclude that any lease or HP will have clauses preventing modification to the vehicle. CMs will be on a case by case basis, but even a fairly broad comment "car to be maintained and serviced in accordance with manufacturer requirements" will rule you out if challenged.

But my other point holds - the chances of the above sequence of events occurring is slim, but it's there all the same.
