I don't see why not? How was your existing heat sink attached? You normally want to use a good thermal transfer compound.

As you can see in the image so it is attached by glue. I tried hard to get it out but it is not coming out.

Some heatsinks are attached with a "glue". Some dry hard and will be a problem to brake off all the glue and apply more. Some stay wet and come off easier.
Some heatsinks are attached with a thermal double sided tape and come off OK.
In all cases you will need to clean the heat sink because it is very important to have good clean surfaces.
Try twisting the heatsink. Then try prying again. Then I trying using bad words. lol

Well with the old board broken and of no use you have nothing to lose removing the existing heat sink. Depending on the glue used maybe place the thig in boiling water for several min and a screwdriver wedged between heat sink and uC. Really matters not since the old unit is scrap. Option two is just make or buy a new set of heatsinks.

I'd try applying heat to see if the adhesive will soften enough for you to remove it. I have a number of heatsinks of that style, but I've never tried to remove one.
