No, you cannot overclock the BCLK on a non-K CPU.

You're just beginning with bclk overclocking, that's perfectly fine. Everyone starts somewhere.
I agree you're right. I've mainly adjusted BCLK on older Core 2 Duo chips. (To be honest, it was quite frustrating. You can't just set the memory speed—it's a multiplier, similar to the CPU. There are only specific options available. So finding the right one often requires a lot of trial and error, plus resetting the CMOS.)
This problem applies mainly to architectures different from Skylake (and possibly Kaby Lake). Skylake separated the BCLK from many other board clocks, making it a practical option for overclocking K-series Skylake or Kaby Lake processors. You don't need only minor single-digit adjustments. Based on what I understand, only CPUs with locked CPUs in Skylake were able to be overclocked this way. It was unofficial, and Intel or motherboard makers quickly fixed it. Now it's still feasible but requires specific motherboards running certain old BIOS versions. This setup may disable features like the iGPU and certain instruction sets.
I transferred my i3 from version 3.1 to 3.2 using the BLCK, keep an eye on memory speed since it will rise—you’ll need to tweak the memory multiplier to maintain consistency. I did this on a PC I received for free at college, and I actually completed the task in class after finishing all assignments. Temperatures were acceptable, but the PSU became quite hot. It was a quick fix from another school that we had to rebuild for the unit.
I have a 4790K processor that's Haswell architecture. It tends to get warm right away, so I'm holding back on adjusting the base clock.
Occasionally it seems to go further than expected, but I won’t be handling the base clock since it’s quite a task. This is just an inquiry about whether it’s possible.
It seems this method was once standard for boosting processor speed. You could choose between a higher multiplier paired with a lower base clock, or a lower multiplier with a higher base clock, and depending on your chip design you might achieve better results with either approach. With Skylake, for example, you could reach 4.6 GHz using either 100 MHz multiplied by 46 or 200 MHz multiplied by 23, though most systems stick to the multiplier setting.
