I suppose you could. But almost no air is going to be moving through it so you won't get any heat from the return. The point of radon remediation isn't to move air. It's to create negative pressure under the slab. Also a radon fan costs about $150 and an HRV costs a lot more. It would cost more than all of the radon stack parts put together.

If you want an HRV so badly just install one ducted throughout your house like it's intended to be used. But first you should address the air leak issues already present in the house. An HRV/ERV is to bring fresh air into a tight house that doesn't get enough ventilation through the walls, basement and attic.

And if you do even a rudimentary job of air sealing your radon issues will increase.
