No, You'd have to run it every page load (Well, Every admin page load,
so use the admin_init hook or so).
WordPress doesn't store most things in the Database, rather, it
dynamically registers everything on each page load. This adds a lot
more flexibility to the platform.

The standard way is to register a new taxonomy and hide the
Categories.. So yes, That's the Elegant UI way.

Your alternative is to add a gettext filter that does
str_replace('Categories', 'Topics', $text) on every single bit of text
in the admin..
