When googling, I met the sentence as follows: Working from home requires that you have strict discipline.

And it came upon me that 'home' can be used as adverb like the following 'Webster's Learner's Dictionary'

▸home adverb
1 : to or at the place where you live
▪ She called home to say she would be late for dinner.

So I googled again to see if it's ok to use 'home' instead of 'from home' in the sentence in question.

Alas, there was no sentence coming up when googled in Google books with 'working home requires' as apposed to 110 example sentences with 'working from home requires.'

I can figure out 'working home' is not ok to use, but don't know 'why.'

Can you give me your wisdom?
Working home is not possible.

This are the proper uses of working as an adjective:

She is a working mom. (She is a mom who has a job.)
He's a hard working man. (He's a man who works hard.)

The home cannot work or earn money.

These are possible:
Working at home
Working from home

OK. Here's my wisdom. "home" is one of more idiosyncratic adverbs in the English language. Trying to figure out "why" is like knocking your head against a brick wall.

You might want to try some head-knocking of your own. That is, you may want to draw your own conclusions just by examining specific examples. (* indicates 'grammatically incorrect'. ? indicates that opinions may vary.) Note how certain verbs allow 'home', and others don't.
