No. Nobody outside of Twitter can repeat the analysis.
First, only Twitter knows which users are active (the population being analyzed are the DAUs). People doing bot analysis from publicly available define activity based on the account tweeting, which will probably skew heavily toward spam bots.
Second, the mDAU metric is the DAUs with known bots having been removed. Nobody outside of Twitter knows which active accounts were excluded by Twitter from the metric. Even if 50% of Twitter DAUs are bots, as long as Twitter detects 90% of them as bots and marks them as non-monetized, the 5% number stands.
Third, nobody outside of Twitter can actually do a proper job of evaluating whether an account is a bot, since they have orders of magnitude more signals than a simple tweet stream / public profile information.
Twitters methology is far better than any publicly available bot detection would be, but the flipside is that it's not a replicable methodology.
