Not really. It's the fans that are trying to equate Diana and Carol. Mostly based on Carol's increased profile on the Avengers titles and all the marketing Marvel dedicates to her since 2012. Carol is the prominent female face for the Avengers nowadays. The same way WW is the prominent female face for the JL.
However, Marvel's investment and constant relaunches for Carol (starting in 2012 we've had 2 under KSD, 1 with the Carol Corps, 1 for ANAD and another one coming this Fall) aren't yielding the equal return.
Looking at the figures from May:
Spider-Gwen leads the pack, followed by Jane Thor, X-23, Gwenpool, Black Widow, Silk, Ms Marvel, Mockingbird and then Captain Marvel.
Marvel should focus all their effort into pushing Kamala Khan more. Kamala has outperformed her idol in sales and reception since her introduction in 2014. Or retool Storm or Sue Storm for a lead role.
