We absolutely could. There’s nothing making it impossible.

There’s just no real reason to do that. My TV is several meters from my couch. Meanwhile, my phone (when I’m using it) is about 1/3 to 1/4 meters from my eyes when I’m using it. The TV is 30-40 times farther away.

Therefore, it’s a lot harder to see the pixels on a TV, than a phone. Thus, the phone’s pixels are a lot smaller, so they can fit much more of them onto the screen, and still have the user be able to see them.

It’s not about how many pixels can fit on a device, it’s about how many pixels a typical user will be able to see.
