Someone spoke about the "motte-and-bailey fallacy" on another thread. I know it's only wiki but I had a quick search and found one of the sub-sections to do with this, on related concepts interesting.
If you view it in respect of the changing, or change in, or attempt to change, the definition of "woman" because forcing the concept of TWAW with the reality of biology is an elision:

"The fallacy has been described as an instance of equivocation, more specifically concept-swapping, which is the substitution of one concept for another without the audience realizing.[5]
In Shackel's original article, he argued that Michel Foucault employed "arbitrary redefinition"[2] of elementary but inherently equivocal terms such as "truth" and "power" in order to create the illusion of "giving a profound but subtle analysis of a taken for granted concept".[2] Shackel labeled this type of strategic rhetorical conflation of the broad colloquial understanding of a term with a technical, artificially stipulated one as "Humpty Dumptying", in reference to an exchange in Through The Looking-Glasss^.[2] In Shackel's description, a motte-and-bailey doctrine relies on overawing outsiders with pseudo-profundity,[2] similarly to what Daniel Dennett called a deepity.[3]
"Unlike normal examples of equivocation where one exploits already existing, perhaps quite subtle, differences of meaning, Humpty Dumptying is hardly subtle. The differences in meaning are so obvious that equivocating by use of them cannot normally be pursued without first softening up the audience. The softening up is effected by convincing the audience that the dual meaning is somehow an exposition of a profundity. ... the strategy is, as in Foucault's "Truth and power", to first make use of the word in its redefined sense, then present the redefinition as if it had already been established as the deeper content of the concept. Finally, the impression of profundity is sealed by passages which elide both meanings at once.[2]""
Of course, fucking Foucault is involved
