Can these tubes be used in a vintage Vibro Champ?

Read through a few articles about your vintage Vibro Champ, and it looks like the consensus is that this tube would work better for the V1 position. V2 would be a 12AX7, V3 6V6, and V4 5Y3GT. It is my understanding the 12AU7 has less gain. You could try a few different tubes in the pre gain to see what you think.

I assume 12 AU 7 is two tubes in one obviously maintains stereo sepeartion Common cathode which is grounded normally anyway ?

To be precise, the 12AU7 is two independent triodes in a single tube. Like any other electronic component, these can be used in all sorts of applications, limited only by the circuit designers imagination and ingenuity. They can by used in audio and RF circuits... These could be used in a stereo design, but they are not limited to that application. The cathodes are not common between each section, and depending on the circuit design may operate at some potential other than ground.
