The cpu (and lack of TPM 2) is only one issue. There would be no dedicated Win11 drivers for your laptops motherboard and this could lead
to problems with performance and stability. Best to stick with the OS that is contemporary with your machines hardware
(Win7\10 with 4th gen Intel). A forced 'upgrade' is possible, but not really worth the effort. I reckon Win10 is the better OS anyway.
btw - One of our machines is a 4th gen Intel (i7 4970) desktop machine, but it is staying with Win10
because Win11 would effectively be a downgrade.
Very doubtful Monopoly$oft will make Win11 more backward compatible. Word is they are already working on Win12.
According to rumor far enough along to be released late 2024.
