I have two physical volumes and I want to remove one - freeing up the disk space for enlarging my home partition.

Your configuration is a prime example on how you will benefit from BTRFS file system (fedora 33). With two subvolumes / and /home they no longer live in two partitions but rather share the entire space available. Space is used more efficiently.
Another note regarding swap, I prefer using swapfiles instead of swap partitions, that’s much more flexible. (Doesn’t work if your LVM is encrypted and you want suspend-to-disk). In Fedora 33, SwapOnZRAM is coming by default…
