How can I use F@H for stress testing?

It doesn't. It'll just dump the WU.
About the 2070 going down to a 2060 maybe. But a 2070 Super to a 2060 definitely won't work.

Do you know this from actual observation, or are you just guessing?

Observation. Swapping out higher end GPUs for lower ones, results in Wu's being dumped.

Which specific swap did you do, and do you have logs showing this? It may also matter how the GPU was changed and if the appropriate driver install was done. But in the past we have seen driver updates done while processing was paused result in the indexes being recalculated. Folding resumed just fine, but with the GPU's swapped compared to before.

I probably have a log somewhere, but considering that I have a good 15 GPUs, I doubt I'll ever find it, as it happened a few weeks ago.
I'm pretty sure it was either an Asus RTX 2070 (blower) or 2070 Super (Gigabyte 3 fan) with a 2060 EVGA 1 fan swap.

Please confirm the GPU Species of the hardware you're reporting.

In addition to other places, about 100 lines from the top of the log, you'll find something like this:

GPU 0: Bus:* Slot:0 Func:0 NVIDIA:5 ...
GPU 1: Bus:* Slot:0 Func:0 NVIDIA:6 ...
