I think you mean remove a category from an article. And, yes, you can do that. On the editing screen, to the very right and in the middle, there's an arrow pointing right. Assuming you don't already have that showing, it gives you a list of things, and at the bottom of it, there are the list of categories. To remove on, just press the trash can icon next to the category, then press Publish. I hope that helps!
