Not according to the MS specs. You have a 6th generation CPU which is not supported. Also you are not on the Dell compatible list so no drivers will be available. And you may have TPM 1.2 which may be supported (another MS vague spec). MS has stated that a system such as yours can download Windows 11 using the Windows 11 image (media creation tool) once Windows 11 is released. However you will not receive updates which could mean security updates and will not included OS updates. MS has been vague about that but lately looks to firmly restrict unsupported systems. Having said all of that will Windows 11 run properly on your system? Absolutely as I ran it on an 8 year old Latitude and it worked like a charm. FYI the system requirement specs are here. And even more here.
Was interested in understanding whether I can change my PC over to handle Windows 11?
