I think you misread the number. There is no CR2023, but there is a CR2025.

The difference among these cells is their thickness, which translates into a
difference in capacity. There is nothing wrong with using a higher-capacity
cell than required, unless (as someone else pointed out), it doesn't make
proper contact.

It's a good idea to keep a separate list of the CMOS settings, "just in case"
you have to re-enter values appropriate to your computer. In principle, any
computer should boot with the default settings.
