Is it possible to remove a story from a group or folder? If so, what must I do? If not, why can’t I remove?

You need to contact one of the group's admins (either Dark Cookie or FamousLastWords) and make a request to change it because only they are able to make changes like that

Just be polite and honest. Tell them why you want it taken off and if they agree, it'll be taken off before you know it. And if they don't, they'll more than likely explain why
