#1. Why would you care if your knife qualifies as a tactical folder if you're not sure what one is? If it suits your needs then it's the knife you're looking for.
#2. And if it's not a true "tactical folder" that doesn't mean it's a piece of crap. A $300 Tom Brown knife isn't "tactical" but it's usefull as hell - and top quality to boot.
#3. "Tactical" isn't so much about the looks of the knife - it's about the function. What makes a car a sports car isn't the looks either.
One essential feature of the tactical folder the reliability of the locking mechanism. When deployed it should be nearly as sturdy as a fixed blade. And it should tolerate a fairly large load without failure (I'm not sure of the exact numbers). Plus it should open consistenly with one hand. And after a couple of years of hard use it should still be functional. Which is important if you're going to be tough on your knife.

That knife in the photo uses a lockback mechanism which isn't as reliable, safe or strong as, say, a linerlock design that many tactical folders use. At a glance I'd assume it wouldn't qualify as a "tactical folder."

But, if it works for you, who cares what it's called?
