Hello and welcome on Ask Ubuntu!
If I want to answer your question, in short, I definitely say no, unfortunately, you will not be able to install Ubuntu on a generic ARM and Android-based tablet.
A bit longer explanation:
As you can see there are lots of architectures which Ubuntu can support through different "image builds", (Sorry at the moment no better term came to my mind) and also different pieces of hardware.
Device drivers built into the kernel are frequently well-supported, and we also have proprietary drivers available from the manufacturer.
Since neither Touch nor a full-featured desktop Ubuntu is supported by most of the manufacturers it is not possible to run.
To run the system you need specific drivers and proper firmware.
As you can see there are ARM builds of Ubuntu (for example for Raspberry Pi *) but they are optimized for the specific hardware or supported out-of-the-box by the kernel or have proprietary support as I said before.
