If you did it as a biologist, sure. Marx's perspective was wider than the field of political economy though. Like, for example Lature commented on a lot of science, and was proficient in it, but is usually recognized as a philosopher / anthropologist and not a scientist.

Marx is usually read as philosophy, but he would have rejected that, arguing that philosophers only reflect on the world, whereas he was both reflecting on the world and changing it in a dialectical process.

He would have wanted to be called a scientific socialist and not a philosopher.
