Is this a literary allusion?

Question

This is from the book The Color Purple. I'm not sure if this is considered an allusion to Uncle Tom's Cabin. The sentence is..."I don't know, say the prizefighter. This sound mighty much like some ole uncle Tomming to me. Shug snort, Well, she say Uncle Tom wasn't call Uncle for nothing."

Answer 1

Yes, any reference to a work of literature is a literary allusion

Answer 2

Yes, that is a literary allusion.
