I'm pretty sure it is the North terminal they are moving to and I can't see all of the U2 management with their Hertfordfordshire homes moving to LGW. They're not going to commute accross London every day.
There's really no reason for the HQ to be located on expensive airport land anyway. A trading estate in Milton Keynes would be far more likely than moving to LGW.
