Somewhat. Colon cancer and rectal caner are usually an adenocarcinoma. They are both located in the large intestine. The difference is that they are treated differently.

Can always being constipated lead to colon or rectal cancer?

Not really, but... Theoretically, constipation allows toxins in our everyday food to stay longer in contact with the lining of the colon, thus exposing the cells to the possible mutagenic effects for longer. One of the ways a high fiber diet is thought to be protective, is it speeds elimination, reducing toxin exposure thus reducing cancer risk. Plus, it tastes good!
Assoc, not cause. Dietary habits that can lead to constipation (low fiber, low intake of whole grains, legumes, fruits and veggies, high fat), can be associated (statistically in populations) with increased rates of colon and rectal cancer. Fiber supplements, vitamin supplements don't help out, diet does. There are other causes for constipation. Discuss with your doc; see a dietician if needed..
