Yes, you could. A high-pass filter that is able to drive a laptop voice coil down to 100 Hz would probably cost about that much, which is 50x more than the motherboard manufacturer wants to spend. A high-pass filter in the DSP/driver software is free, sell a million Chromebooks and that's $500k of pure profit from cutting costs. Unless you account for warranty recalls due to buggy drivers, in which case a 0.1% failure rate is enough to make this a bad idea.
