Is it possible to disable the save changes warning when opening a project.

even if you could it would be highly suggested that you didn't, lord i don't know how many times that function saved me because i was using hot keys and hit the wrong one.

You can do it in max for live, since you've got access to the dialog messages.
It's really useful in some situations.

I just need it for live playing, hard to find the Don't Save button on stage

I find it easier to drag the new set in, then delete the tracks I'm no longer using. Makes for more seamless transitions and you don't have to go through the muck of opening the set with the file tab.
