For a full wave rectifier, can it rectify an AC wave with a DC offset above the rated voltage of its diodes rated voltage if the peak to peak voltage of the wave is within its rated voltage? Like if you had a rectifier that with diodes that could work up to 10 volts, and you were rectifying electricity with 100 volts DC and a 5 volt amplitude sine wave ripple, would it work because the AC component is only varying by 10 volts?

Sounds like a bad idea considering how cheap diodes can be. They should be rated at 3 times the AC voltage to have a 50% safety margin. Remember the peak DC value will be 1.414 times the RMS value.

There may be a best practice forbidding this, but I suspect it's OK. Each component must be rated for the voltages that will pass across it, so you must make sure the circuit is designed so the offset voltage will never be applied across the components of the rectifier. I won't write this as an answer because I don't possess the necessary degree of certainty.

No, you can't do that. If you have 5V peak-to-peak riding on top of 100V dc then two of the rectifier diodes will always be forward biased. The other two diodes will see a combined reverse voltage that varies from 95V to 105V. On the other hand, it really doesn't make sense to use a rectifier when the input voltage is always positive.
