RF layout bend over Component
Yes, a smooth bend would be better for signal integrity than the square corner. All other things being equal, that corner sticking out represents an unnecessary impedance "bump" in the transmission line. Although in this case, the dimensions are so short that you'd probably never be able to measure the difference. The solder fillets on the nearby components also create impedance changes of about the same order of magnitude. And making the turn within a component pad makes the question moot anyway.
