Inspectng the code in all.equal.numeric, I find

You could use
2*abs(A-B)/(A+B) < 0.1
which avoids an apply().
I've assumed you meant different by under 10% of the mean of the two, hence the
2/(A+B); if you meant 10% of something else, s

In essence I want to check whether A and B equal other give or take 10%.

Yes,
checkRange = function(A, B, range = 0.1)
{
A>=B*(1-range) & A<=B*(1+range);
}
Test:
A = c(67, 24, 40, 10, 70, 101, 9)
B = c(76, 23
