No.  Physical partitions are either Primary or Extended.  Extended
partitions are just containers for Logical partitions, so can only be seen
by the partitioning programs.   Extended partitions only contain Logical
partitions.  Either Primary or Logical partitions can contain filesystems
or "logical volume groups" (LVM) which in turn can contain
multiple "Logical volumes" (which contain filesystems).  The only advantage
of LVMs is that a volume (or group) can span physical partitions.
