As long as you comply with the GPL, this is perfectly acceptable. Note that this includes making source code available and allowing licensees to redistribute your OS freely, so charging for your version might not be the most effective way go make money—I could just throw up an iso torrent for free—but it could work.
RedHat, for example, charges for RHEL (packaged with support). CentOS was a famous fork that originally only changed trademarkable features (names and logos) and charged one vent per copy. This didn't stop RedHat from becoming a profitable venture, of course.
