Basically no. You can find out some that aren't supported (although the online device lists tend to lag a bit behind the state of kernel development, and it may be that a device listed as unsupported now actually does work). Sometimes supported devices stop working, as a result of a problem introduced by a change to the kernel. There's no easy way to know when that will happen because the kernel developers don't have examples of every possible type of device and couldn't test them all even if they did. It also happens quite frequently that a device is supported but doesn't work on one particular computer because of hardware bugs. Obviously it's impossible to predict when that will happen, although certain classes of bugs can sometimes be identified (like when a particular vendor's motherboard has a known problem). But this means that sometimes even supported devices don't work.
