systemd version the issue has been seen with

Used distribution

Debian, but irrelevant AFAICT

In case of bug report: Expected behaviour you didn't see

I can rename an interface with a udev rule or a .link file

In case of bug report: Unexpected behaviour you saw

networkd is faster and enables the interface before udev gets around to renaming it.
Unfortunately, an interface that's up cannot be renamed

In case of bug report: Steps to reproduce the problem

# cat /etc/systemd/network/10-en0.link:
[Match]
MACAddress=aa:bb:cc:dd:ee:ff

[Link]
MACAddressPolicy=none
Name=en0

Reboot a couple of times. Sometimes the interface is renamed correctly. Sometimes it is not.

Workaround:

# cat systemd-networkd.service.d/after-udev.conf 
[Service]
ExecStartPre=/sbin/udevadm settle
