Actually, you can, in counted cases Copyright Game Mechanics, see: Shadows of Mordor: Nemesis System and Bandai Namco "Auxiliary Games" (Mini-Games during Loading Screen)
Creative Outlets as well as Game Developers could be sued if they made from scratch something remarkably similar to those Game Mechanics
It looks like the game is part of Chrome but not Chromium, so it would be under Google's copyright. So if you mean a copy using the same assets then no. If you mean can you create an endless runner featuring a dinosaur, yes
Could they sue the hell out of you, block the game on app/play store and generally make your life miserable if they felt like it even if it would not hold up in a court: Yep.
