Install Notebook Win 10? Compatible?

I wanted to buy the following notebook:

Since there's no operating system, I wanted to buy Win10 afterwards:

The Win10 product stands for PC. Does it matter? Could I still install Win10 on the notebook without complications afterwards?
Do I have to pay attention to anything else?

Only the manufacturer or seller will be able to guarantee you 100%.

However, it would be quite a disgrace to sell laptops these days that are not Win10 compatible.

A laptop is a portable PC.
