Opening bid in first seat
Tl;dr: No, bid 1♠.

There are many different sets of bidding conventions in bridge. In the one I learned (some further information here: http://www.rpbridge.net/3j00.htm), 4♠ is a preemptive bid that signals a very long spade suit (which you have) and several points below the regular opening strength of 12 high card points. Your hand is too strong for that (even if you play where the unprotected Qs aren't worth points), so you should bid 1♠ instead and then further tell your partner about your amazing spade suit by rebidding it at your next opportunity, probably jumping a level when you do so (e.g. 1♠ - 2♣ - 3♠).

While other conventions may differ somewhat, it is unlikely that any will tell you to open 4♠ with that hand. This is because, although your hand is quite likely to make 4♠, if your partner has any strength you might be able to make a slam instead, but if you start the bidding high then there's very little bidding space for you and your partner to figure that out.
