In short, no.  If you want to do runtime testing of software on Cygwin, 
you'll have to run Cygwin on Windows.  That being said, you could run 
Windows in a hypervisor (such as VirtualBox) and try running Cygwin in 
that VM.

A Cygwin cross-compiler toolchain and compatible packages are available 
for Fedora 14 and up.  The release RPM needed to install these via yum 
or PackageKit is available at:
