If your assertion is accurate, it's presumably an overreaction to concerns about being sued for redlining. But that's irrelevant here, to the point of being utterly off-topic. Meta's policy poses no risk that knowledge of your present address would be used to discriminate against a protected class. Instead, it is part of your duties as an employee: Live in this house.

You would first have to establish that that duty has a statistically significant harmful effect on persons over 40 that it does not have on other groups. This will not be easy, people under 40 have families, too!

It will be further complicated by the fact that the same effect occurs simply by virtue of a workplace being in a remote, hostile environment, or having work hours incompatible with a typical family life, requiring a limiting principle, which you have not provided.

If you pass that hurdle, Meta would have the opportunity to establish that the policy is based on a reasonable factor other than age. The court would have to find that Meta's policy and/or its purposes are unreasonable. That seems unlikely.
