Historically, they sounded different, so they wouldn't even be acoustically in-tune w/ the same notes. Each would only be in tune with its nearby notes on the "extended" cycle of fifths.

What does this mean for a piano keyboard, for example? Is the fact that it's the same key related to the fact that a piano cannot be perfectly tuned?

Yes, and it means that songs actually sound different when played in different keys. It's not just a shift up or down, the intervals within the song shift, if only slightly.
