I can't say what you can or cannot use. Laptops are very fickle when it comes to memory so what WILL work on one system, may not on another. And what WILL work with one module, another module may refuse to work with. The best option would be to get two matched modules and install those. The second best option would be to get another module of the exact model that's already installed. The third best option would be to compare the speed, CAS Latency and voltage and get a module that at least has the same specifications. Beyond that, it's a crapshoot and you may have to just take your chances and hope for the best.

I don't usually have issues with memory working together, even when there are some minor differences, but occasionally, they...

Unless you're running professional level applications, there's little probability it would do you much good. I'd recommend installing an identical 4GB module in the second memory slot for a total of 8GB which should be sufficient for most any gaming or consumer applications. Plus, if your unit supports dual channel memory operation you'll want two compatible modules with very similar or the same specifications in order to take advantage of that. Using disparate modules, with one being 4gb and one being 8gb, will probably, almost certainly, not do that.

Dual channel operation doubles the effective bandwidth, which IS beneficial, whereas adding memory beyond what the system actually requires usually is not.

Optimally, you would want to use a matched set, purchased TOGETHER, to guarantee compatibility. Otherwise, you definitely would want to at least get the exact same model number for two identical model number modules. Next option, but less likely to "play nice" together would be getting another model that DOES have the same speed, voltage, latency and chip density as the one you currently have installed. What is the model number of your current module and where are you located?

I don't usually have issues with memory working together, even when there are some minor differences, but occasionally, they won't. That would piss you off, so be prepared for it if you do anything other than purchasing a "matched" set that's been verified for compatibility.
