Well,
FC 23 seems to use the same format as debian: (gzipped cpio archive)
# mkdir /tmp/foo
# cd /tmp/foo
# gzip -d < /boot/initramfs-4.4.6-300.fc23.x86_64.img | cpio --extract
60527 blocks
# ls
bin dev etc init lib lib64 proc root run sbin shutdown sys
sysroot tmp usr var

DESCRIPTION
This manual page documents version 5.11 of the file command.
file tests each argument in an attempt to classify it. There are three
sets of tests, performed in this order: filesystem tests, magic tests,
and language tests. The first test that succeeds causes the file
type to
be printed.

Mine is the same
but:
[root@study-localdomain ~]# mkdir /temp/foo
mkdir: cannot create directory ?/temp/foo?: No such file or directory
[root@study-localdomain ~]# mkdir /tmp/foo
[root@study-localdomain ~]# cd /tmp/foo
[root@study-localdomain foo]# gzip -d <
/boot/initramfs-4.4.6-300.fc23.x86_64.img | cpio --extract 60527 blocks
gzip: stdin: not in gzip format
cpio: premature end of archive

And if you run "file" on the image file directly without running it through gzip first?
i.e.
file /boot/initramfs-4.4.6-300.fc23.x86_64.img
?
Note also that you shouldn't have the "60527 blocks" on the end of the command you've quoted - that's the output of the command when Steve ran it. It should just be "cpio --extract". However, that's not the cause of your error.

What does:
file /boot/initramfs-4.4.6-300.fc23.x86_64.img
say?
