I think the conventional definition of a "fat bike" is something with tires at least 3.5" or 4". Most current fat bikes have tires in the 4.8" to 5" range. A 2" tire would be considered a fairly standard mountain bike tire...and the "plus" sizes seem to be in the 2.6" to 3.2" range or thereabouts. So a 27.5+ size would be a 27.5" x 2.8" for example (or 70-584 to use the more precise ISO nomenclature).
If you have a bike with 2" wide tires, you can certainly ride it on the road. You can ride a fat bike on the road as well, with 4" tires. Depending on the tire design and construction, it may be a pretty inefficient haul, but it's certainly doable.
