Hi Greg,
Based on your description, I suspect that you actually have the original Surface Laptop and not a Surface Laptop 2 that this post was filed under.
You can see the Surface devices that are upgradeable to Windows 11 at Which Surface devices can be upgraded to Windows 11? - Microsoft Support.
To answer your specific question, the minimum processor that supports Windows 11 is the 8th generation Intel processor and as you noted, your device has a 7th generation processor. This does not meet the requirements.
The detailed list of supported processors is available at Windows Processor Requirements | Microsoft Learn.
Hope this helps,
Greg
