Can moderators add/edit/remove subcategories within the category they moderate?

Hi Liz Dollmeyer , only users with the admin role can add or edit categories and subcategories. If you are a category moderator, you can manage the moderation queue, approve and remove posts, as well as edit and set post statuses in the categories you are assigned to. If you are a global moderator, you have this ability for all categories in the community including private categories. If you have the admin role, you can also change community settings, assign moderators and manage categories.
