Using the current device's product key on my another device.

I don't think so, not now. If the other PC was still running the original install where that key was entered, Yes, you could find the key. Once you reinstall Windows, and skip entering a key though, its not there to be found. The current Product ID will I think be based on the generic key. @Superfly knows more about that product ID stuff than I do.

My Product Key

I have hit another roadblock in my marathon two-day attempt to restore the laptop that Windows 10 destroyed. I do not have the product key for the device, so cannot even revert to Windows 8.1. The product key is not shown in the Amazon purchase listing for the device, and I long ago lost the paperwork. Is there any way I can look it up (keeping in mind of course that the device itself is utterly unusable in its current state)?
