Splet2. Technically you can, but the MSE function is non-convex for binary classification. Thus, if a binary classification model is trained with MSE Cost function, it is not guaranteed to minimize the Cost function. Also, using MSE as a cost function assumes the Gaussian distribution which is not the case for binary classification.
