Not very likely.

Any intelligent life must likely have:

1. A hardened brain case or exoskeleton. If intelligence is an evolutionary asset in a certain environment then the brain or its analogue is worth protecting.

2. Some sort of appendage (hands, beak, trunk, tentacles, antennae, etc) that allows fine manipulation of objects, necessary to develop tools.

3. Some form of terrestrial locomotion to allow the development of fire.

None of these three premises needs a humanoid shape.

This, for example, is an imagined form of a sentient "dinosauroid", had the K-T extinction event never happened. It's one of the most realistic and creative sentient "alien" species designs I found on the net, speculative evolution at its finest.
