What happens if you charge a four pole capacitor with a lower voltage on the input than rated? Is the output still the rated voltage?

Do you mean a four section electrolydic capacitor for power supply application? If so the voltage ratings on all sections must be at, or higher that what you are trying to replace.
Yes, for power supply usage. But I was just wondering theoretically, if you put 12V on the 2 input poles of a Jensen four-pole, and it's rated 63V - do you get 12V on the output as well then?
I just have basic knowledge of electronics, I'm just curious about this.

No

Power supply smoothing capacitors do not make the voltage higher or lower. They just smooth it to get rid of noise, ripple, spikes etc.
The capacitors voltage rating is the maximum voltage allowed.
So a capacitor rated 63V can be used for 12V (or 25V or 40V etc) but not e.g. 70V or 100V.
This is important - if too high a voltage is applied to an electrolytic capacitor, it can explode and cause damage or injury.😱
