Of course, but bilinear is much softer, ie. blurrier. Its all a matter of tradeoffs, especially when you stick to "normal" filters. Lanczos is sharper, but rings more.
Some people prefer sharper images, some people prefer the blurier, but cleaner look of softer interpolation.
There is no "correct" scaler.
