I'd still like to know which Nano CPU you have and how much RAM.  There
are things that can be done.

"No more room on the disk" is WAY different than "There is room, but I
should have partitioned it differently."  The question IS, is there and
where is there room?

If there is room, in particular on your partition 4 that could/should
have been an extended and you want to do this without the help of
another drive, e.g. USB thumb drive:

1) tarball the 4th partition FS, if the resulting tarball is too big for
   any of the first three, depending on whether there is is room to
   tarball it in itself, you can:

a) tarball it in chunks of directories and distribute those tarballs
   across the other 3 partitions, or

b) use "split" to cut the 4th partition's tarball into pieces that can
   temporarily reside on the other three.

2) fdisk the drive, delete the now sacrificable 4th partition as a
   primary, reallocate it as an extended, and create a 5th logical
   partition, and more.

3) format a FS on the 5th partition, and restore the tarball--use "cat"
   to put the pieces back together if you had to use "split".

Normally how I partition a development system drive is make from a few
to several ~20GB partitions, 1-3 & 6-(n-1) (5 is a swap partition) and a
"large" last partition for a "storage heap".  And I never use GPT--I
can't predict how I may need to get to them in the future!

(So I ain't buying an "inexperienced" argument. ;-) )

But the point is that Linux development keeps moving the prereqs.  My
development on my mini-ITX Via "Esther" 1GHz C7 (Pentium-3 equivalent)
systems is going to stay at a (B)LFS-6.6 level with minor updates, e.g.
OpenSSL, etc.  The hardware just won't support much more without getting
way bogged down.

I never use GPT because: 1) in a rescue situation I might have to use
something that doesn't have that support, and 2) most drives have a few
to several versions of my own LFS build versions and some of those,
which I could use straight away, don't gave GPT support.

OH, that's not an argument that will fly in IT!  Let me introduce you to
Rear Adm. Grace Murray Hopper, "Amazing Grace".  (The Navy kept trying
to retire her, but they could never make it stick.)

Agreed, but not necessary!  See above.

Good.  Playing with toys is a great way to learn.  My Via Esthers are
"toys".  Their mini-ITX boards are in little cases about the size of a
large-ish dictionary.

Not going to quit suggesting copying a LFS you made on your HP to the
laptop, and using a chroot to get in and rebuild the kernel to
accomodate, would be a good thing to play around with!
