Well...
There are bicycle tires out there that can be used w/o tubes and still stay air-filled. There are also solid tires which don't need either tube or air.
So, staying strictly true to your question - yes, you can ride a bike w/o a tube.
But if you're asking about if you can ride a bike on a bare metal rim, then the answer is - yes, but poorly.
Traction is horrible, making it a scary, unsafe ride. You'll slip & slide all over the place.
It's also really uncomfortable, and very, very shaky.
On top of that it'll quickly damage the rims beyond the point of them ever being useful again.

It can make your tire unevenly filled, which will give you a bumpy ride.

When you ride a bike from Chengdu to Tibet you need a spare tube, tire levers, a tool box , cell phone and a pump.
That's like asking how do you ride a bike without a bike. It doesnt make since.
You can ride a bike or a train.
