Is it valid...? Yes.
The compiler largely ignores line endings and line breaks (since they're 
inserted mainly for formatting, not syntax purposes).
One exception is string constants, so your parser will have to track the 
"'" character and ensure a corresponding later match within the short 
line, or else insert a forced concatenation.
The code

type
PInteger = ^
integer;

has readability shortcomings, but compiles without a murmur.
