This is not true, the issue was fixed quite some time ago:

[root at boson ~]# dnf erase kernel                                                                                                                                     
Dependencies resolved.                                                                                                                                               
Error: The operation would result in removing the booted kernel: 
kernel-3.17.4-200.fc20.x86_64.

This is definitely a good advice. Even though most of these issues are caused 
by poor packaging of various Fedora rpms, it helps a lot to know what exactly 
happened. See this page for more information on how to report a bug so it's as 
helpful and descriptive as possible:
