Is it possible to update my 2010 MackBook Pro to the latest IOS? I currently have 10.15.7 version.
For the late 2010 High Sierra 10.13 is end of the line. If you managed to let it run 10.15 it is most likely a slightly newer model but if it is from the 2010/2012 era it is end of the line for your MacBook
No. Even if you have a 2012 model, the last supported OS is 10.15.x.
FYI, to get the exact model of your Mac you can either click the Apple menu and select "About This Mac" or by entering the system serial number here:
Check Your Service and Support Coverage - Apple Support
Unfortunately the "Axxxx" is only a series identifier which is much too broad for identifying a specific model. Even while a series may have some similarities, they also have as many significant differences. It is too bad Apple doesn't actually make that number an identifier for people.
A1286 looks up to 15-in MacBook Pro including models with the same shape case from 2008 through Mid-2012.
