It would, but unless the rod is a fairly large part of the volume of the cylinder (which would be unusual), you wouldn't see massive advantages in the amount of air moved or the pressures reached.

Coaxial configurations are those where the chamber is around the outside of the barrel. In terms of how they work, they generally use what is effectively a barrel sealing piston valve (although they have occasionally been seen with things like QDVs instead).
It's a quite compact layout, but it tends mean less chamber volume, usually means you can't breechload* (although some people have gone out of their way to disprove this), and occasionally have problems like like aligning the barrel inside the chamber and making sure that muzzle loading doesn't accidentally push the projectile into the valve. (Although, to be fair, barrel loaders can have different problems).
* Which means I personally take issue with their safety. No breech-loading means either means pressurising a loaded cannon, or trying to muzzle load a pressurised cannon. (Both of which are more dangerous than loading the projectile only at the last step, while you're safely not anywhere in front of the muzzle).
However, many people would consider me overly paranoid about that, but I'd rather that I not be responsible for any news articles that include any permutation of the words "died of potato inflicted head trauma".
