So yes, a component or “module” can be broken up into smaller parts. You’re contradicting what you said here:
If all logic is in the same component, it doesn’t necessarily mean the same class! (In fact it most certainly does not in most cases!). So yes, all GUI code should be in its own COMPONENT but that component can (And should if we follow SRP) be split into sub-components, or submodules as you just referred to them.
Again this goes back to your misuse of SRP/SoC. In this scenario a component fulfils a concern, that component may be made up of many classes. SRP is applied at a class level, not a component level. This has been explained to you by Scott and others on at least a dozen occasions.
Let’s put it this way: If SRP and SoC are the same thing, why do they have different wikipedia pages?
