It should be fine - it's just that there are the 0.1" pins at the back edge of the board that could potentially touch it.
I'm pretty sure that's the aerial, so all it'd do is stop the radio transmission. If you power up the board and it appears as a bluetooth device then everything's fine and there's no need to do anything.
Even if there was a problem you should be able to (very gently) pull up the aerial end of the board and run a soldering iron along the soldered pins - as long as you can get it lifted a fraction of a millimeter so it's not touching you'll be fine
