Yes, after installing Fedora, perform a classic installation of a Windows 10 ISO on the machine, make sure that it uses the remaining space and does not delete the Fedora partitions (otherwise, try again).
In your BIOS, select the boot order, if a Fedora entry exists, put it first, otherwise the bios will usually suggest creating a custom entry: \EFI\fedora\grubx64.efi, don't forget to place this custom entry first in the startup order. This procedure and its necessity depend on the type of computer on which the installation is made.
Since Windows 10 Falls Creator (October 2017), it seems that Microsoft takes into account (sometimes) the existing grub and does not rewrite it, if you install Windows 10, remember to check the version of the downloaded ISO.
