Yes, sure. When one can install more panels it frequently makes financial sense to save money buy buying a smaller inverter and spend it on panels. The clipping of power around solar noon is more than compensated by the additional power generated in the morning and afternoon.
But the OP is constrained in space, Tesla only sells one class of panels (340W) at present, and have either 3.8kW or 7.6kW inverters. charlessj recommended (originally, and that's what I responded to) that the OP ask for the smaller inverter. That advice was wrong: the OP can't add panels, so the only result would be unnecessary power clipping in the middle of the day. The fact that the smaller inverter would be maxed out for a lengthy period is a worse outcome than not maxed out at all.
