Like camera gear placed into zip lock bag to help acclimatise to wildly extreme humidity differences, it probably would. You can see the condensation immediatly inside lenses but of course not inside the laptop.
My post was based on the fact that although extremely high humidity most likely won't damage the hardware itself, the LSIs could potentially be tripped, giving Apple an excuse to deny warranty. Personal experience.
Note: I'm really basing this going from cold AC airports to extremely humid environments (90-100%) outside quickly.
