Yes, you can. My wife has a vigorous sourdough starter and she likes to bake in the oven, but when she is away or too busy, I just whip it up in the bread machine. Choose the longest setting, if possible, for the rise. It makes pretty consistent loaves for me this way. If it isn't getting a good enough rise, try through a small amount of bread yeast in too if available. It will get an extra rise from the yeast, but still carry the sourdough flavor.
