For unity3d, Linux is not mentioned as an option in https://unity3d.com/unity/system-requirements , so I doubt if it's possible. Maybe better ask in their own forums in https://forum.unity.com/ .
A laptop is what it is. You can add RAM and replace the hard disk, and that's it.
From our review https://www.cnet.com/products/lenovo-ideapad-110s/review/ : "The Lenovo Ideapad 110S is a simple but capable budget laptop for those with basic needs and who don't want to make the Chromebook leap.' Your need is not basic, I'm afraid."
Moreover, it seems it usually comes with Windows 10. Why did you overwrite this with Linux?
