msg: hostname module cannot be used on platform Linux (Neon)

I recently upgraded to Ansible 2.3 for KDE Neon support and ran into the
following failure when running a playbook against it:

msg: hostname module cannot be used on platform Linux (Neon)

There is noting about Neon in the source
https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/system/hostname.py

And this is the task it failed on:

   - name: set hostname
     hostname:
       name: "{{ host }}"

Has anyone found a solution or workaround to this?

IIRC Neon is based on Ubuntu, then you should be able to do this

- name: set hostname
   copy:
     content: "{{ host }}"
     dest: /etc/hostname
