I've tried running MCO under Wine on Linux Mint 17.1, but there hasn't been any success. Maybe using PlayOnLinux could give a different result? I'll have to see...
On the other hand, MCG works mostly fine on my Linux system (through PoL, but that uses Wine anyway).
I say "mostly" simply because the screen is a bit cut off on my monitor, but that could just be something on my end that I haven't checked.
