No, the treasury of Macedon was a slender one, and Philip squandered it all on professionalising the army and creating the system of Macedonian hegemony in Greece, which was no cheap thing to do. The sheer amount of bribes he'd have had to pay out to his Greek faction leaders in the cities, as well as the cost of upkeeping the Macedonian troops who occupied the more troublesome cities in order to impose the hegemony, and the fact that the Common Peace, as it was called, did not include a provision for the remittance of tribute to Macedon, meant that financially speaking it was a bit of a dud investment on Philip's part. He'd have been better off conquering them and ruling them openly as a tyrant, instead of trying to pretend and hide his intentions with the fiction of the Common Peace. The Greeks weren't wearing it anyway, so you may as well have brutalised them. At least you wouldn't lose so much money that way
But he didn't. And the result was that Philip was heavily indebted at the time of his assassination, and Alexander inherited the debt. It's what made the early campaign in Europe and in Asia so precarious - he had to win, he had to plunder a few cities and he had to capture some slaves which he could put on the market. He desperately needed cash to pay off his debts. Losing wasn't an option.
This is why Memnon of Rhodes' Fabian strategy for the war was a good one. If the satraps had listened to him and scorched the earth, there would have been no money for Alexander to find even if he took Lydia and Caria and Mysia. And if he had no money, his creditors would ruin him, the army would disintegrate if they weren't getting paid, and the Persians could have stepped in to crush a crippled Alexander. They would have been welcomed with open arms in Greece too, as the liberators of the Greeks from the tyrant Alexander
