The more I dig, the less certain I am of what's going on.

I made a small program that does what svn_io_remove_file2() does.

Snippet const char* path_to_nonexistent_file =
  apr_status_t apr_err = apr_file_remove(path_to_nonexistent_file, NULL);
  TRACE(_T("apr_err = %d\n"), apr_err);

  apr_status_t status = apr_file_attrs_set(path_to_nonexistent_file,
  TRACE(_T("status = %d\n"), status);

  apr_err = apr_file_remove(path_to_nonexistent_file, NULL);
  TRACE(_T("apr_err = %d\n"), apr_err);

And the output is:

  apr_err = 720005
  status = 720002
  apr_err = 720002

If I run the program a second time, I get the same output again.

So, the first error is a EACCESS, then the non-existent file is made
writable, then a ENOENT error is generated.
It doesn't make sense to me, but I think the bottom line is that the
second apr_file_remove call can generate an ENOENT result and if the
ignore_enoent parameter is TRUE, then the function should return
SVN_NO_ERROR after the second (or third) try.
