Question can you mix a 16gb with an 8gb (same company, same speed)

You're talking about RAM here, right? Brand doesn't matter, the speed mostly does. If one stick had a lower speed, the faster one would lower its' speed to the speed of the slower one.

This would get you to 24GB of RAM, but it won't work in dual channel.

Maybe is always the correct answer when mixing memory. Generally if there is a timings and speed mismatch of any kind, the memory will default to the slowest JEDEC speed on the sticks. If it boots from there you can then manually set the speeds and timings. (Many OEM boards don't offer these settings, this mostly works with consumer boards)

Some motherboards will support flex mode and allow the 8GB stick to be in dual channel with the first 8GB of the second stick.

You can also do things like 4+4GB in channel A, and 8GB in channel B and get full dual channel. Sometimes requires the 8GB stick to be doublesided and the 4GB sticks single sided. Motherboards often have a little chart showing the population rules on the board.

Mix and match RAM is always a gamble. It might work at reduced clock, it might not boot, it might be OK, it might cause random blue screens.
Matched sets of DRAM are sold for a reason. The manufacturer guarantees that the parts work as a set.

A simple question, and a simple answer... maybe.
The caveat is that it may work, work with issues,may not work at all, and may or may not run in dual channel mode or flex mode.
To get a better guess, provide the make/model of your motherboard,cpu,
the make/model of your original ram and the make/model of the proposed ram.

OP

could work, but you could also get a BSOD from doing such a thing.

the guy who worked at the mall store where I often buy parts warned me not to do something like this.

If you want a fast, stable and error-free system, don't mix ram sticks/models/sizes/speeds etc......

If you don't care about these factors, then go for it :D

Whether it will work will depend solely on how particular your mobo & cpu are about ram configurations.... some are VERY finicky in this regards, others are less so,therefore as with most things pc-related, YMMV !
