Unless you really want to pretty much reinstall that computer I would
just add the spare partition as a physical volume. Add it to your
volume group and then grow your logical volume. Otherwise, you'd have
to destroy BOTH partitions to make one big partition.

Also, this kind of arrangement is what LVM is good at. You are already
using LVM so you wont see a performance hit by using two physical
volumes rather than one. (At least, not compared to just using the raw
partitions.)
