That is indeed possible and it does fit in a broad sense, however, there is another archaic meaning that may fit the context litter better.Someone who is impolite....mean spirited.
"selfish person who is unwilling to give or spend, miser"
The vile person shall be no more called liberal, nor the churl said to be bountiful. (Isaiah 32:5)
"The instruments also of the churl are evil: he deviseth wicked devices to destroy the poor with lying words, even when the needy speaketh right." (Isaiah 32:7)
In both verses wealth seem to be the key point.
