Yes, you can use the same call on two Skype devices at the same time.

Since I lack a webcam but have one on my tablet, I’m avoiding using the tablet’s headset. I’m using my PC and often need audio with headphones on, so I’m checking if voice chat and video can work together.
You might consider signing in on both devices and joining a call, though I’m skeptical. The simplest option seems to be creating another account for your tablet and using it for your tablet, or vice versa for your PC.
