Normally the answer is no. But in this case you can and not only that, you replace the video card BY replacing the processor. You have AMD A series, which is called an "APU" not a "CPU" because graphics rendering is handled on the processor chip. So with your A4 processor you have embedded AMD 7420G graphics. If you upgrade to an A10 processor you will have 7660G graphics. Still by no means gaming quality, but significantly better. And these AMD A series mobile processors are very inexpensive now.
So yours is one of the few cases where we can even discuss a processor/graphics upgrade on an HP consumer laptop.
