You mean the brownish transparent keys ? Yes they are the same. But I think you can't exchange the all keyboard as the connector ribbon is not of same length .
As for the case, I don't think the bottom part would fit , as the connectors are different on the back (SCSI for the Lombard, FW for the Pismo).
Maybe the top part of the case with the trackpad... never tried.
The all screen assembly can be swapped between the two.
