It can, but in my opinion, don't upgrade to windows 11 if you are on windows 10 right now. What I have heard is that the battery optimization is awful for laptop, especially for laptops that don't ship with windows 11 by default. Maybe just stay with windows 10 for a bit while they figure out all that stuff. But if you really want to, then yes it can probably handle it. Unless it is from 2007. I can help you out a little more if you can give the model of it and some more info as your original post is very vague. Hope this helps!
