Yes, you can use canned chickpeas as a substitute for dried chickpeas in black chickpea sundal. Canned chickpeas have already been cooked and are ready to use, which saves you time. However, keep in mind that canned chickpeas tend to be softer than freshly cooked ones. Rinse and drain the canned chickpeas before using them in the recipe. Adjust the cooking time, as you will only need to heat them through and allow them to absorb the flavors of the tempering and spices. While canned chickpeas work well in a pinch, some prefer the texture and taste of freshly cooked chickpeas.
