I've been using the Technical Preview on a couple of my computers since it was available.
FFXIV hasn't had any issues or caused any issues I've seen. Testing was done mostly on a Surface Pro 3 and my desktop on and off.
However, if you happen to use a PS4 controller on PC (like me), the programs normally used to customize the controller (DS4Tool, DS4Windows, InputMapper) have an issue with Exclusive mode. I know the DS4Windows/InputMapper guy's working on fix.
NOTE: There was an Nvidia driver issue (technically Nvidia's fault, but it was pushed through Windows Update) that caused issues with multiple monitors. Have a current installer already downloaded on your computer if you happen to have a Nvidia graphics card. ((AMD users, just uh...have fun with Catalyst control Center bugs as normal))
