I have a 20GB 4th gen that's acting up and I believe it's the logic board. Problem is it seems that's a pretty common problem as well as HDD issues, bioth of which exceed the value of the working iPod.
Your question though - I believe you should be able to swap the smaller drive into the 20 GB. I tried a 40 GB 3rd gen drive in my 20 GB and, while I couldn't close the case, I was able to ascertain that the HDD was not causing the problem I was having. If the 10GB drive is thinner, you may want to shim it to keep it from rattling around. They used a foam padding on mine.
Also, you might be able to swap the screen into the 10GB - or not.
