Do you reckon it is safe to clean install windows 7 on a laptop that came with windows 10?

Laptop Specs:
Lenovo Ideapad 510
Intel Core i3 6100u 6th Generation Processor
4GB DDR4 RAM
Windows 10 Home pre-installed but I upgraded to Enterprise

Wipes a hard drive, needs a new license, possible issue of no driver for a function.
Pain in the rump. Also:
Intel HD Graphics 5500
Processor is 2.30 GHZ Why do you want to do it? Windows 7 will stop to be supported by Microsoft in 2017.
