Yes, you can use RST with Fedora, but you have to import the RST
metadata into mdadmin before you partition and install the OS. There are
a number of articles out there you can read that describes the process.
Google is your friend. Note that you'll use mdadmin to manage the RST
stuff when running Linux and the RST tools that come with Windows when
running Windows..
That being said, I've never done this in the installer as I never dual
boot Windows and Linux using the same physical disks. For the (very) few
times I must share a machine between the two, I have one set of disks
for Windows and a separate set of disks for Linux.
In my world, Windows gets run in VMs with Linux as the host OS. Thus, I
use mdadmin and its metadata natively for my RAID stuff as I don't have
to share that metadata with Windows. Preferably, I use a _real_ RAID
controller--but they can be expensive.

Thanks Rick. Ultimately I plan to run this pre-installed Win10 in a VM
under F29. The trick is to get a forensic copy of the existing
pre-installed OS that I can read back into a VM using P2V. I'm not
planning to dual boot. Note that this is a laptop (on steroids!), so using
a "real" RAID controller is not feasible.
