The real question you should ask
@lordrt is not if you can... but if you should. What is the benefit of doing so? What will 11 allow you to do that 10 (LTSC or Pro) will not. We also need to consider, that running windows isn't hard. You can run it even with 512 Mb ram and a single core. The issue is what do you do after with the applications, with the browsers and internet, etc.
As long as you can have an SSD (for speed) windows 11 will boot ok, especially some of the lite builds. Disable indexing if you have lots of files, Cortana, and Defenders Real-time protection, (do a manual scan when needed), you will boot surprisingly fine. Windows after 8 are very dependent on disk speed. Try a 16 core with a 5400 rpm disk and then a dual-core with SSD. The 2nd will win hands down. Keep in mind that newer OSes were made to support new hardware technologies. Things like direct storage (needs dx12 card and nvme disk), Windows subsystems (android and linux), better handling of multicore CPUs, and so on, will not have any effect on you due to your PC not having those.
At the end of the day, OSes are free here, all you have to do is give win11 a try and see for yourself and the system. If it is not what you hoped for, use a 10 build (start from LTSB). Just to be clear, I'm not saying it can't be done cause it can. Just pointing out that there may be no real benefit.
Hope it helped.
