reading a file with other read permissions set

For this question assume a file with 604 perms in a directory with 700 permissions. Assume this file exists: /test/file

A non-root user can techincally read that file but in practice to read it the process must be given the pathname to the file, and the kernel will check that the directory /test has the executable bit set. Because it is not set, the read will fail.

If the one does a chmod o+x /test, then a non-root user can do a cat /test/file and read the file. Is there a way to read the file without setting the execute bit on the directory /test.?
