You have the right to do so. This subject was discussed at length here in the past if you do a search.

The guy who builds the particular equipment should be the guy you listen to regarding mix ratios. In others words, if Stihl says to mix their trimmers at 50:1, then you should follow that advice in lieu of what is printed on the side of an oil bottle.
You may want to pay more attention to the wording in your Stihl owner's manual. I've got two pieces of Stihl equipment, and both of them just say that if you're using Stihl 2-cycle oil (which they obviously recommend), then you should mix it at 50:1 ratio. They don't say what ratio should be used if you're using someone else's oil.
Another example is fuel additives/system cleaners for your car. Have you noticed that different ones should be added into your tank in different proportions? Wonder why?

If Amsoil figures their Sabre is good enough to run at 100:1, then I know it will definitely be good enough (better) at the Stihl recommended ratio of 50:1.
My guess is that Sabre is more concentrated, so you need to use less of it. Why do you assume that more oil is better? By the same logic, if 50:1 is better than 100:1, then surely 5:1 should be even better than 50:1, right?
Too much oil can foul your plugs and possibly cause other issues.
Sorry Quattro Pete. We will just have to disagree here based on your comment above. I never implied "more oil is better". I am saying that the recommended ratio provided by the equipment manufacturer is the one that should be followed, regardless of what you may think the "concentration" level of a given two-stroke oil is. Even Amsoil, which I use regardless but at 50:1.
You talk about me implying that if I think 50:1 is better than 100:1, then I must think that 5:1 is better than 50:1. Absolutely incorrect, Quattro Pete. I think that 50:1 is better than 100:1 because that is what the Stihl engineers told me to use. If Stihl thought 5:1 was better than 50:1, then that is what they would recommend. Surely they don't, however, because of spark plug fouling and exhaust blockage issues.
Please remember, Quattro Pete, that I am not currently using nor suggesting to use "more" oil. I am using 50:1, just like the guy that built the equipment said to do. If the 100:1 Amsoil Saber is more concentrated as you suggest, then that is great. I guess I am then using a fantastic oil at the equipment manufacturer's suggested mix ratio. I don't see any other logical path.
