I've checked a few places such as reddit and Qmadix. The consensus is it cannot be removed without damaging the liquid glass or the phone. There seems to be a lot of complaints regarding this type of protectant.
[http://www.qmadix.com/support/liquid-glass-faq.asp|Qmadix] doesn't exactly say "no", but their answer is "Interesting but why would you?".
[https://www.reddit.com/r/Staples/comments/41f0t8/how_do_you_remove_liquid_armor/|Reddit]'s response "not possible".
