Systematic oppression does not in any way need to be directed from the majority group to a minority group. Take, for example, South African Apartheid, where a minority white population was oppressing multiple other ethnic groups. If we're talking about systematic oppression, all that matters is that the relatively small group with power in the society feels and acts negatively towards a some group of Others.
As far as weight goes, there is apparent some research which indicates being overweight significantly impacts your ability to climb the corporate ladder, which is a common theme among other oppressed group. It obviously isn't the same as race or gender, as someone who is overweight can (in some cases) change their weight, while someone who is Black can't change their skin colour, but they are definitely similar issues.
No.
