Mmmmm, not really. pressing down on the lid puts all the pressure on the lid and not where the leak is.
I *think* the only way to check for a leak is to remove the airlock and seal the opening and then press down on the lid. (If there isn't a leak you shouldn't be able to.)
Or you could do a brew with the opening sealed-- when your fermenter explodes you look at the rupture; if it originated from one specific location then you had a leak-- if it got turned to ribbons then you didn't.
