There was a problem hiding this comment.
This needs to have an issue number (even if there's no issue, so here you can put the PR number, i.e. 52084)
Also, I think this would fit better in the "Other enhancements" section, as that's where some other error messages are?
Finally, the note needs to be user-facing and can't mention private methods. How about "Improved error message when creating DataFrame with empty data, no index, and wrong number of columns"?
… the visible behavior for the library user instead of the behavior of a private method.

The following example incorrectly triggers the ValueError saying that "Empty data passed with indices specified."
