At one time WD40 was the most recommended gun oil on the market. Millions of guns were cleaned and lubricated with WD40 and most of them still function. I seriously doubt that removing cosmoline with WD 40 is going to do anything to harm the gun. Moreover, all the OP has to do is take the stock off and blow any excess WD 40 off the gun. There are no boxes or parts on a 91/30 to hold puddles of WD 40.
I own a safari grade BAR that was made in the 1930's. I have hunted with it for over 30 years. It was cleaned with WD 40 for at least 20 years. I will make book it looks better than any wood stock gun you own. The gun has had parts replaced due to signs of wear. It seldom malfunctions and has never broke.
I have several other very nice guns that still look like they are new after a lot of care with WD 40.
Science has provided us with better lubricants and I use the newer lubricants now. I wouldn't think the world was going to end if WD40 was only lubricant available.
