  Yes.  it's safest to do this kind of thing in single user mode, but if
you're not familiar with this, it still works in multiuser mode (i've done
it many times).  Run swapoff on the swap device, run fdisk and delete the
partition, recreating a new one of the proper size (assuming the swap and the
freespace are adjacent as you said they are).  Toggle it as Linux Swap (type
82 I think?  look it up in the list....).  then take note of the new device
name (ie /dev/hda6 or something like that).  Exit fdisk, saving the changes. 
You _may_ have to reboot at this point.  If you do, just log in as root and
continue (it will tell you if you have to when you exit fdisk - saying
something like "error writing partition").  Now run mkswap /dev/hda?
(whatever hda device your swap partition is).  Then swapon /dev/hda?.  That's
it!  Beware that you can toast your linux installation doing this if you
touch the wrong partition.  Be careful and read all the documentation on the
programs you are using.  I take no responsibility for anything you break. :) 
Playing with partitions is always dangerous.
