Almost

The pins on the bottom are different.

All the connections are the same except the filaments- the 6CG7 needs 6.3V between pins 4 and 5, while the 12AU7 needs 12V or you can also run the 12AU7 on 6.3V by tying pins 4 and 5 together and then applying 6.3V between them and pin 9.

The 6CG7 of course can handle more current having twice the plate and cathode area. But otherwise it and the 12AU7 are similar geometry.
