'Start' does have another meaning, though: 'to jerk/move suddenly from suprise':
The loud bang caused the little girl to start.
The rabbit started from the side of the road.
In these, you can't replace 'start' with 'begin' and keep the same meaning.
I am planning to start a new business.
I'll start to make breakfast.
-- Here you can also use "begin," although I would say that "start" is more natural.
I am going to start my engine so that I can drive to work.
-- Here "begin" would not work.
I would imagine that there are situations where "begin" would be preferable. I don't know of any rule, however. Perhaps others do.
