They're very close companions but not quite synonymous.
D&D 4e introduced the paragon tier concept to describe a level range (11-20). We've also got paragon paths, which are bundles of skills & benefits a D&D 4e character obtains over the course of the paragon tier.
So we've got questions about paragon paths, but also questions not specifically about paragon paths but about things during that level range (e.g. How to build a Thief in Paragon tier, What Paragon-Tier modules can I use to showcase the Underdark?, How can I view Paragon Tier feats in the Character Builder?).
It's weird and they have a significant overlap but I'd leave them separate since they're fundamentally separate game concepts. I've added some usage guidance to both tags.
