Theoretically any glass vessel can be used.
If you browse lava lamps on ebay, sometimes you can come across lamps made from vodka and whisky bottles. So yes a soda bottle should work, but it's all about getting a right sized coil, and the right density of wax and masterfluid and for that I am well out of my depth.
If you are transferring contents from a lava bottle to your soda bottle you should be okay. One further thing, make sure that your glass soda bottle has a nice thick base. And finally the very best of luck with your project. If successful, lets have a photo of it.
