In my opinion, the you should change your config settings to not to mount the swap space when the system boots, then do an orderly shutdown and reboot.
Then you will be OK.
Sorry, I did not look at your system and think about how to configure it to not mount and / or use swap when it boots, but if you configure your system to not use swap when it boots, then you reboot in an orderly way, you should be OK.
I don't recommend just "deleting" that space without an orderly plan / method to first boot without the swap, and then after you are comfortable all is working as you expect, you can reclaim the disk space as you wish.

swaplabel
SWAPLABEL(8) Linux Programmer's Manual SWAPLABEL(8)
NAME
swaplabel - Print or change the label / UUID of a swap area
SYNOPSIS
swaplabel [-L label] [-U UUID] device
DESCRIPTION
swaplabel will display or change the label / UUID of a swap partition located on device (or regular file).
If the optional arguments -L and -U are not present, swaplabel will simply display the swap area label and UUID of device.
If an optional argument is present, then swaplabel will change the appropriate value of device. These values can also be set during swap
creation using mkswap(8). The swaplabel utility allows to change the label or UUID on actively used swap device.
OPTIONS
-h, --help
Print help and exit.
-L, --label label
Specify a new label for device. Swap partition labels can be at most 16 characters long. If label is longer than 16 characters,
swapinfo will truncate it and print a warning message.
-U, --uuid uuid
Specify a new UUID for device. UUID must be in the standard 8-4-4-4-12 character format, such as is output by uuidgen(1).
AUTHOR
swaplabel was written by Jason Borden <jborden@bluehost.com> and Karel Zak <kzak@redhat.com>.
AVAILABILITY
swaplabel is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
