Yep. My wife's still running a MBP from 2012 that I think finally got its last update to Big Sur (released 2020) without issue. Looking at the compatibility charts, everything from 2015 on-ward supports Monterey (2021, the latest version). The last laptop that couldn't update past El Capitan was 2009. As far as Macbooks (non-pro), last one stuck on El Capitan is the 2009 model as well. And it's not even that Apple broke anything on the 13 year old laptop, it's just that the rest of the world moved on and they're no longer fixing it.
