At the moment No.
I got the Get Windows 10 notification on my ATIV Tab 5 and when I clicked to proceed, it was displaying the compatibility issue: Intel Graphics Media Accelerator - The Display manufacturer hasn't made your display compatible with Windows 10. Check with the manufacturer for support:unhappy:
Short answer is no. Spoke to Samsung and they said they would not support Windows 10 on the ATIV Smart Tab's. Pity really as I like using mine, although my older Dell Mini 1012 is compatible.
