Yes, but it won't do it the way you are thinking.  All the partitions would
be part of the Volume Group, and would be parcelled out as Logical Volumes
with no regard to your scheme.  It is more flexible than using fixed-size
Basic partitions, but it is less safe, as there are both Basic partitions
and LVM structures.  Note, if you have allocated space to a Logical Volume
and sized the filesystem on that volume to use all the space, in order to
move space to another Logical Volume you would need to 1) shrink the
filesystem, 2) shrink the Logical Volume it is on, 3) grow the desired
Logical Volume, 4) grow the filesystem on the desired Logical Volume.
