If by "today", you mean the twenty-first century in which you are asking your question, there is no way that Emily could represent today's woman. William Faulkner's "A Rose for Emily" was originally published in 1930, and cannot represent women born some 85 years after its publication and some 53 years after its author's death.
If what you are asking is whether Emily was intended by Faulkner to represent a woman of the 1930, then the answer is also negative. Emily is meant to represent a woman of the old, pre-civil war southern aristocracy, a type that was vanishing in Faulkner's day. Unlike the women of the 1930s, she was born in a time that had much more restrictive class distinctions and sexual mores. The women of the 1930s are portrayed as less bound by class distinctions and unwritten social rules than Emily, but also seem less imperious, lacking a sort of faded grandeur that Faulkner associates with the Old South.
