You can change the name, but to do so requires you to change the app metadata in XCode, rebuild a new binary, and upload it back to iTunes Connect like you would any other update.
That would trigger another round of reviewing, so in theory you shouldn't be able to "sneak" a name change past Apple.
Just a few days ago, 'The EagleBook' changed its name to 'The CIA World Factbook', for example: http://itunes.apple.com/us/app/eaglebook-cia-world-factbook/...
