If you mean can I create a macro in Word that will simply hide a tab on the default ribbon, then the answer to that is no.
You can do it with a document or template, but as that also requires manipulation of the ribbon XML code to provide the hooks for VBA to be able to hide the tab, it is probably simpler all round just to edit the ribbon itself - hence my suggestion.
If you want to dig deeper see
