I'm going to snip the co-text, but I'm keeping it in mind.
I'll come armed
This means that the cop is going to be armed when he comes.
I'll come eaten
This means that I'm going to be eaten when I come.
Grammatically sound, but semantically nonsensical.
Generally you can only verb-of-motion past-tense when the past-tense describes an act that you will have been done to yourself (Or to the subject of the main clause.
For instance:
- I will come dressed = I will come, having been dressed
- I will come armed = I will come, having been armed
- He will come groomed - He will come, having been groomed
... etc.
If you want to say that you have come, having eaten beforehand... well, that's probably the only way to say it:
- I will come, having already eaten
In your example, the due date is already Monday, so you are asking for an extension of time on the due date.
extend the due date to Monday
is incorrect in your example, since the due date is already Monday.
end of the day Monday
may mean the end of business-day Monday, which is not what you want.
end of Monday
is closer to what you mean. However, to avoid ambiguity, teachers will usually specify
due by midnight on Monday
So you would be asking for an extension until 1 minute before midnight, which is essentially midnight. In the current age of electronic assignment submissions, it can be easily enforced.
If your teacher only specified "Monday", you would have a valid argument that midnight is still a valid time to submit your assignment.

Welcome to Ell Stack Exchange.
There's nothing wrong with the sentence presented. But the adverbial phrase of time "on Monday" works best at the end of the sentence as follows:
I'll be back from (my) leave on Monday.
Besides, the use of the verb "be" is a bit informal in the scentence. Instead, you can say as follows:
I'll return from leave on Monday.
I'll come back from leave on Monday.
The following sentence is quoted from The Free Dictionary:
Pete will be back from holiday next week.
