Not really. I mean there will always be lots of argument over what makes a game an RPG. Technically any game where you play a role would fit the dictionary definition... of course that makes games like Mario and Zelda RPG's, because you play the character you're controlling.
Generally the common interpretation is that to be an RPG a game needs to be about choice and consequence, where it's based more on your stats than reflexes. Where your character and how you "build" them is what determines the gameplay.
That's why games like the new Fallouts and Elder Scrolls games are argued over, because while they have tons of stats and there's choices and consequences, the gameplay itself is all twitch based, meaning player skill completely invalidates character skills. If you're good at shooters, you'll win Fallout 4 easily, even if you don't build your character to be good with guns. Often those are referred to as Action-RPG's.
Meanwhile a game like Baldur's Gate, Planescape: Torment, Pathfinder: Kingmaker are more accepted as "traditional" RPG's because a player's skills and reflexes aren't what determines success. It's all about character builds and strategic choices.
For Cyberpunk, it can MAYBE be called an Action-RPG. The problem is, again that stats make very little overall impact on success in the game. They might affect playstyles, but even without building up your gun skills, you can win shoot outs just fine based on player skill alone.
Plus the game is linear as hell. There are some "choices", but they're extremely shallow and have no real effect on the game as a whole. It's usually more along the lines of "do the quest or not". Most story quest choices don't really affect the story at all, they're just a matter of if you go Path A or Path B, both of which are functionally the same and lead to the same destination, so they're meaningless choices.
I'd call Cyberpunk an open world (a very poor one unfortunately) shooter with RPG elements. While there are stats and such, mostly the game is played as a straight up shooter focused on player skill and reflexes.
I like the game, and am having fun with it, but I wouldn't recommend it to anyone who's looking for an RPG.
