are the psu of an lcii and lc475 swappable?

i wanna test an lc2 with the psu of an lc475 so i can confirm the psu is dead

Way back when Apple offered LCII to LCIII upgrade and then an LCIII/III+ to LC475 upgrade. Those upgrades replaced the motherboard and the cover (kept the PSU). So an LCII to LC475 PSU swap would definitely work, and I would think it is highly likely to work the other way too.
