The first question is why. It sounds like you want Ubuntu but the
bootloader and kernel built by Yocto. I'm struggling to see what this
would achieve.

Hi,

My comments are in-line.

... a legal battle maybe?

Bring in the lawyers!

I would also ask:

"What is your use case?"
"Did you ask Canonical?"
"Does Canonical allow you to do this?"

From [1]:

"Copyright licensing[1] and trademarks[3] are two different areas of law, and we consider them separately in Ubuntu. The following policy applies only to copyright licences. We evaluate trademarks on a case-by-case basis."

From [4]:

"
You can download, install and receive updates to Ubuntu for free.

You can modify Ubuntu for personal or internal commercial use.

You can redistribute Ubuntu, but only where there has been no modification to it.

You can use our copyright, patent and design materials in accordance with this IPRights Policy.

You can be confident and can trust in the consistency of the Ubuntu experience.

You can rely on the standard expected of Ubuntu.

Ubuntu is an aggregate work; this policy does not modify or reduce rights granted under licences which apply to specific works in Ubuntu.

Any redistribution of modified versions of Ubuntu must be approved, certified or provided by Canonical if you are going to associate it with the Trademarks. Otherwise you must remove and replace the Trademarks and will need to recompile the source code to create your own binaries. This does not affect your rights under any open source licence applicable to any of the components of Ubuntu. If you need us to approve, certify or provide modified versions for redistribution you will require a licence agreement from Canonical, for which you may be required to pay. For further information, please contact us (as set out below).

"
We do not recommend using modified versions of Ubuntu which are not modified in accordance with this IPRights Policy. Modified versions may be corrupted and users of such modified systems or images may find them to be inconsistent with the updates published by Canonical to its users. If they use the Trademarks, they are in contravention of this IPRights Policy. Canonical cannot guarantee the performance of such modified versions. Canonical’s updates will be consistent with every version of Ubuntu approved, certified or provided by Canonical.
"

"
You can use the Trademarks, in accordance with Canonical’s brand guidelines, with Canonical’s permission in writing. If you require a Trademark licence, please contact us (as set out below).
"

"
You can use the Trademarks in discussion, commentary, criticism or parody, provided that you do not imply endorsement by Canonical.
