When will products purchased in California become un-serviceable? This question answers the question in places for most cases.
According to their warranty
Products purchased in the state of California, United States, as
required by statute
So it appears that items are serviced and are repaired longer in California yes?
Best Answer
Residents of California can obtain service and or parts for up to 7 years under the Song Beverly Consumer Warranty Act.
First, what Apple terms "vintage" and "obsolete" are not in anyway bound legally to what California law provides for. For the record, Song-Beverly provides for manufacturers making parts available for up to 7 years; Apple can, in it's discretion, make "Vintage" in 8 years.
Secondly, the law only allows for replacement parts and service information be made available.

What's most important here, is the context of that warranty point you brought up:
(emphasis mine)
TL;DR
The Song Beverly Consumer Warranty Act says that the manufacturer (Apple) must make available parts and service information for up to 7 years on your electronic device (MacBook) that was purchased in the state of California. This doesn't extend the warranty to 7 years.
