Authorizing line up and wait on intersecting runways is permissible.

Line up and wait on a runway is a clearance to enter and align on the runway and hold there until further clearance to take off. On intersecting runways, allowing this creates a real risk because another aircraft could be using the crossing runway and move through the intersection area while you’re waiting, which could lead to a collision. For that reason, you don’t authorize line up and wait on intersecting runways. Controllers would instead hold you short of the intersection or sequence you for takeoff on a runway after ensuring the crossing traffic is separated. The idea isn’t about time of day or needing extra approval; it’s about keeping runways deconflicted and preventing path conflicts at the intersection.
