Yes they can be daisy chained you just loose reaction time of each switch. In practice for Limts this is not a problem as the delay is in milli secs which is more than acceptable. I wouldn't daisy chain them and share for Home switches because you want the fastest reaction time you can for repeatabilty but for Limts they are fine chained together.

One thing I do for limits to save on switches is to use traveling switches and just have them triggered by a Target at each end of travel, less wiring and things to go wrong.
