When are previous version of MATLAB at end of life?

When do previous version of MATLAB reach end of life and/or end of support?

For Example 2020a and 2020b. I see they are not listed on the roadmap, but wasn't sure what the criteria is for when the older versions lose support.

Not sure but those are new enough that they are still supported. If you did have like a 15 year old version, it would probably still work but if it didn't, tech support, or Answers might still be able to help you even if they can't run some antique version. How old were you plan on letting your MATLAB version get before updating?

Note: If you have a current subscription to MathWorks Software Maintenance Service: 1) MathWorks will respond to technical questions and provide workarounds when possible for a period of two years from the date when MathWorks discontinued support for an operating system

Note that it refers to the operating system not the release.

Mathworks regularly discontinues support for older MacOS versions or Linux distribution versions. However, Mathworks is slow to discontinue support for old Windows versions. For example the current timeframe, R2023b, will be the last one with technical support for Windows 7 SP1 -- which was originally released in October 2009.
