The previous recipe was to use qt4-config, which is no longer working as you can't select a qt4 related theme.

A bit late to the party, but the only thing I found was zooming.

Don't know if it will work on Fedora, but on my Ubuntu I could achieve it by simply editing skypeforlinux bin and adding --force-device-scale-factor attribute:
sudo nano /usr/bin/skypeforlinux
nohup "$SKYPE_PATH" --executed-from="$(pwd)" --pid=$$ "$@" > "$SKYPE_LOGS/skype-startup.log" 2>&1 &
nohup "$SKYPE_PATH" --force-device-scale-factor=1.3 --executed-from="$(pwd)" --pid=$$ "$@" > "$SKYPE_LOGS/skype-startup.log" 2>&1 &
