Hi Jeremy Mittel
Thank you for posting here in Community.
MFL should be useable on the Surface Pro.
If the tech can use the Surface Pro device or something similar (with a pointing device or mouse instead of touch), and the device is using Windows 8.1, then it should work.
Related experience: A user has successfully run MFL on the Windows Tablet through the regular desktop functionality on both the touch screen and the clip on keyboard. No major issues were encountered.
I think you are aware, based on your post, but letting you know in case you are not. There is a planned mobile app for SMAX Spring 16 that will work on Windows tablets. So this may solve your MFL issues.
