Linux is a kernel. Fedora uses this kernel, and therefore is a Linux 
*distribution*, such as many other (see http://www.distrowatch.com for 
example). All distributions (note this term) which use this common 
kernel are "Linux", so to say. All these distributions look and feel 
like Unix, they are Unix clones.

FreeBSD does not use the Linux kernel, but has its own. FreeBSD is based 
on one of the original Unices, namely BSD Unix. Therefore, it is Unix, 
but not Linux.

HTH.
