If I want to replace all occurrences of byte with unsigned char, a simple #define will do it. Is there any way to do the reverse with a #define? Grouping two words with either single or double quotes doesn't work, nor escaping the space between them with a backslash. Is it even possible?

The difference between "Is it possible" and "Will it be possible" is that the first question is about the present and the second question is about the future. When we ask "will it be possible" we are referencing a point in time in the future.

It means "How is that possible?" with a little more emphasis since "even" is included. If it is still not clear, I can try to explain better.
adjective [v-link ADJ] If you say that it is possible that something is true or correct, you mean that although you do not know whether it is true or correct, you accept that it might be.
The identifier in a #define statement cannot contain spaces, at least in C.
The controlling part of the C11 standard (though this is essentially the same in earlier iterations) is 6.10.3 Macro replacement /9-10 (combined below):
A preprocessing directive of the form
# define identifier replacement-list new-line# define identifier lparen identifier-listopt ) replacement-list new-line# define identifier lparen ... ) replacement-list new-line# define identifier lparen identifier-list , ... ) replacement-list new-line
blah blah blah ...
An identifier (as used in those directives) is specified in 6.4.2 of the same standard and does not list the space character as one of the allowed ones.
