I was wondering if there is a way to move a pixel from point B to A, and then everything left of this pixel, assuming B is to the right of A, is condensed in the image, and everything to the right would be stretched. Thanks in advance.

There's not really any "moving" involved. Let's say we start with this image and we are going to stretch everything to the left of the blue line at x=200 till it meets the magenta line, and squidge everything right of the magenta line at x=400 so it fits the remaining space:
#!/usr/bin/env python3
from PIL import Image
# Load original and ensure RGB
# Original created with ImageMagick using:
# magick -fill yellow -background black -size 600x100 label:"Some squidgy text" image.png
im = Image.open('image.png').convert('RGB')
# We are going to stretch everything left of x=200 to x=400 and squidge everything from x=200 to x=400
A, B = 200, 400
# Get left and right part of original image
Lorig = im.crop((0,0,A,im.height))
Rorig = im.crop((A,0,im.width,im.height))
# Stretch left and squidge right
Lnew = Lorig.resize((B,im.height))
Rnew = Rorig.resize((im.width-B,im.height))
# Copy original and splat new left and right parts on top
res = im.copy()
res.paste(Lnew,(0,0))
res.paste(Rnew,(B,0))
# Save result
res.save('result.png')
Note that you could combine the extraction and stretching into one operation, I just chose not to for pedagogical reasons.
Here's an animation for extra fun:
