I think nowadays clear meaning and comfort on the ears are what matters here, rather than the strict formal rule. Yes, "fewer" is still reserved only for plural countable things. But the use of "less" is much more flexible in modern speech and should not be restricted only to singular or non-countable things.
For example, "less" sounds better when referring to measures of time and distance, because when you say "10 minutes" or "10 miles" we aren't really counting something there. It's sounds awkward to say you have "fewer than 10 minutes" left. You could also put money in this category with time and distance. Don't say "I have fewer than 10 dollars", because less just works better. We think of the "10 dollars" as a singular bulk amount, not as a count of ten times one dollar.
Also in cases using the negative "no less than", this usually works better than "no fewer than" even when referring to plural countable things.
There are lots of other cases where "less" just works better in modern usage even when it breaks the rule.
