Welcome to the Community Forums.
Invisible First-Defense+ Liquid Glass-Screen Protector is not certified for the machine by OEM so we cannot assume much if that would be safe or will not be a factor for functionality. While the machine is within warranty we cannot suggest using such as additional protection for your screen.
For LCD care and cleaning instructions it is placed on attention :
"Never spray or pour any liquid directly on the keyboard or LCD panel!"
Hope this helps answer your query.

Checking with Lenovo quick pick (accessory locator tool) do not show any recommended screen protector.
If the physical silicone/glass protector fails for you then it would be best to call in technical support to inform for the possibility of liquid glass application would be allowed within warranty.
