You'll be limited by how long the flex tail is that connects the monitor to the mainboard. Chances are it's pretty short.
There are some standard connectors (with various pinouts, but you don't care in this case), and if the Mini 9 uses one, you could get a longer cable. Signal integrity concerns on the LVDS will limit you to about 10" on a flex tail or 18-24" on twisted pair. The cable won't be cheap at all (think $50+) in small quantity.
