Yup, for the fedora logo you'll need to ask for permission
https://fedoraproject.org/wiki/Legal:Trademark_guidelines#Non-software_goods For the Red Hat logo, see
http://www.redhat.com/f/pdf/corp/RH-3573_284204_TM_Gd.pdf :
« The Red Hat “Shadowman” logo is also a registered trademark
of Red Hat, Inc. It may not be used on any products without
Red Hat’s express written permission. The only way to obtain
permission to use Red Hat’s “Shadowman” logo is by entering
into a written license agreement with Red Hat, Inc., signed by
both Red Hat and the licensee or by qualifying under or
complying with the “Trademark Permissions” set forth in these
Guidelines. Absolutely no exceptions. If you are a publisher
of software, books, t-shirts or any other products, you may not
use the Red Hat “Shadowman” logo unless you have entered
into a written agreement with Red Hat that allows you to do so
or you qualify for use under the “Trademark Permissions”.
[...] You should contact tmlicense@redhat.com, and we will discuss
possible arrangements with you »
However, it's worth asking them, especially as it does not cost you much. I can help with this if you want.
