In brief: YES!!!
You are confused because they are both done on your back but a spinal tap is to obtain the liquid that in in your nervous system around your spine and brain.
A bone marrow aspiration is done in the iliac bone to obtain a sample of cells inside the bone cavity where blood cells develop and grow.

In brief: Yes
Spinal tap removes part of the cerebrospinal fluid (the fluid that surrounds the brain and the spinal cord) usually by placing a needle into the spinal column through the back and withdrawal of the fluid.
Bone marrow aspiration is done typically by a much larger needle (trocar) which is inserted into the center of the hip bone (rarely the sternum) for the purposes of withdrawing the bone marrow.

In brief: SPINAL; BONE MARROW
A spinal tap does not enter bone.
In a bone marrow aspiration, the needle is injected directly into the bone to extract the marrow.
