In the Learn365 Admin Center, you can change course titles and URLs.
This article describes where to change the title and URL of a course.
Change the URL and title of a course
Courses and training plans are created as pages in the SharePoint course catalog site. Course and training plan titles and URLs can be edited from the Learn365 Admin Center using the training configuration panel.
For e-Learning and Instructor-Led Training courses, the way to edit the title and the URL is similar and is done via the Basic Details section of the course configuration panel.
NOTE
Changing the URL doesn't change the title of the course.

Thanks. I've done this on Classroom training courses, but had an issue with it breaking an elearning course, where the Learning Modules were erroring out. Just tried it again and appears to be working fine. Glad I ran across the article and re-tested it.
