is there a way to remove the tile backsplash without ruining the greenboard behing it?
Only if the tile was not attached very well. Removing tile from greenboard will always remove some of the paper. Depending on what is toing back on there you may just skim coat the bad spots or replace the greenboard - usually replacement is the way to go.
I hope this DIY network exercises their right and sues you. On this very page just to the right it clearly states, " No advertising is allowed".
