I have already identified 5 relevant SNPs in 23andMe results. Confirmation work is moving forward on a number of these. I am running a discovery rate of 7-9% for the submissions to my project. Let's see if I get these labeled correctly....
M228+ under S116
P36+ under J2a1b*
rs35690250+ under R1b-U106*
L86+ under S116
and what appears to be M359+ under J2a
There is a lot more to understand around how many SNPs are relevant and their prevalence even though the 23andMe sample is limited to 1921 SNPs.

23andMe doesn't do sequencing, just probing of a specific list of
already known and already studied SNPs. For the Y chromosome, I count
just 1921 SNPs reported. If we assume that they have tested 15,000
customers with Y chromosomes, the total output is only about equal to
the total number of sequenced bases in one Y chromosome. That means
there should be only a handful of novel, parallel mutations in the
whole lot. I don't know what the error rate is for their testing,
but I fear there might well be a similar handful of errors among so
