Yes - though it seems to be implicit rather than stated explicitly.
For example:
RFC 1906: Section 3.1
"Each instance of a message is serialized ... onto
a single UDP datagram ..."
(and repeated in RFC 3417)
RFC 768: Fields
"Length [a 16-bit value] is the length in octets of
this user datagram ..."
So a UDP datagram cannot be larger than 65K,
which means an SNMP PDU (at least when using
the standard UDP transport) cannot either.
It's not immediately clear whether the same limit holds
for the other transports discussed in RFC 1906/3417.
They also talk about the mess fitting into "a single
datagram", but you'd need to check the relevant transport
specs to see what limits this would imply.
