You need to define a code system, but don't necessarily need to have a CodeSystem instance that exposes the codes. (Though validators will spit out warnings that they can't check the codes if they can't find a CodeSystem for the specified Coding.system url.) If you want to constrain the set of tags allowed, you'll need to define a ValueSet and bind to that ValueSet in your profile.
