The "A" does represent flux linkages but not any flux linkages. Only the
flux linkages that are due to the current causing the flux. From the text
"The number of flux linkages are equal to the magnetic flux multiplied by
the number of times the flux is linked. The flux therefore must be obtained,
which can be found by the flux density". All of the inductance equation
derivations should start from this simple ratio.

	Not sure what A represents in your expression, but it seems to fit very
well with the definition I learned in physics class longer ago than I
want to think of.

	Inductance = flux linkages per unit current

which appears to be the same if A represents flux linkages.
