[Purge] During the purge is it legal to overthrow the government?

No. 

Some of the few laws that exist on Purge day include: government officials "ranking 10 or higher" must remain unharmed, the use of weaponry above "Class 4" is forbidden, and police and emergency services are suspended. Anyone who doesn't follow the rules is executed.

The whole point of the purge is so that America is "cleansed of its undesirables". Which means the wealthy and powerful can sit back in their fortified bunkers surrounded by heavily armed guards while the poor, minorities, and everyone who isn't part of the elite kill and maim each other. It's literally about keeping the government in power, and letting their friends reap the economic benefits. 

A mob of people could certainly try to organize and march on the homes of those in power, but they'll be cut down by the best defenses money can buy. And if any of them survive to the next day, they'll be executed for breaking the law.
