Although I have answered this point at SharePoint 2016 web application could not be extended I will add here additional info by answering your specific questions one by one.

Will removing extend web application affect the content database?

No, The main Web Application and the extended one will share the same Content Database, and removing the extended web application will not affect the content database.

Why extended web applications are not listed in the Manage web application page in central administration?

It's normal behavior, only the main web applications will be listed on this page.
