Not really, no.
More like arguing that Satan is a central figure for LaVeyan satanism, ie The Church of Satan (Satanic Temple is the more… rational one of the two, although both value reason.)
And while neither believe in an actual Satan in the Christian sense, they do value him as a symbolic adversary.
So it definitely wouldn’t be wrong to say that the Church of Satan has people who “worship” Satan.
Nice try but no dice. Also, theology is far less objective than “what is the prescriptive meaning of anarchy” which isn’t s terribly hard question to answer.
A philosophical movement is defined by its philosophy and followers not by the word it calls itself.
So let’s go back to what the most basic information on this we have: the Wiki article. Which begins:
Anarchism is a political philosophy and movement that is against all forms of authority and seeks to abolish the institutions it claims maintain unnecessary coercion and hierarchy, typically including the state and capitalism.
So where exactly doesn’t it mean these things…?
