The tool works in this use-case unless something has broken it recently.
It can be done, the convert tool should work, and Btrfs should work on any device mapper
instance. However…
In the context of the default ext4+LVM layout the conversion still means separate /boot,
/, and /home file systems. A major benefit of the Btrfs layout is these are subvolumes,
which instead draw space from one volume pool. And that's lost with a conversion
strategy. It also means going from a Fedora "standard" layout to a distinctly
non-standard one because our Btrfs layout isn't like the result you'd get from
what you're talking about.
