It does have an analogous feature, the MBP's trackpad is huge and you probably touch it by accident all the time.
It's just that Apple's system tries to separate deliberate touches from accidental ones, rather than disabling the trackpad input completely.
You used to be able to turn this on and off (it was called "Ignore accidental trackpad input" in the trackpad preference pane) but now it's an always on feature. The trackpad has extended so far into the palm rests that it would be very difficult to use without it, and the feature works well enough that you don't even realize it's happening.
