Yup!
There's two main benefits to using sliding bearing blocks: to better support the bearings and to be able to tension the chain. I'm not a big fan of adding tensioners where they might be unnecessary, and had pretty good luck running exact C-C #25 chain drivetrains in 2015 and 2016.
So the question is then, is putting the bearing straight in the tube sufficient support? This is game dependent; large impact loads on your wheels could cause the bearing holes to start to turn into ovals. However, for most games which have no or relatively small field obstacles, bearings straight in the tube should be fine.
