No, they are allowed by the syntax.  They are not valid.

    The path segments "." and "..", also known as dot-segments, are
    defined for relative reference within the path name hierarchy.  They
    are intended for use at the beginning of a relative-path reference
    (Section 4.2) for indicating relative position within the
    hierarchical tree of names.  This is similar to their role within
    some operating systems' file directory structure to indicate the
    current directory and parent directory, respectively.  However,
    unlike a file system, these dot-segments are only interpreted within
    the URI path hierarchy and are removed as part of the resolution
    process (Section 5.2).

It doesn't matter what is the result of processing

> file:/x/..//y
> file:x/..//y/

because those are not valid file URIs.
