Can Guangzhou ride a bike to Foshan?

It is not allowed in theory. Beyond the operating area of mobike in Guangzhou (and, too much).

If the car is returned beyond the operating area, the charging method is every half hour 100 yuan.

The way to exploit a loophole is to ride out without locking the car and go back to Guangzhou after locking the car. It's equivalent to that you've been renting ... but it's a little expensive.
