Could you add a ref in support of this point? And which Noether theorem are you referring to?
For your other question, just search for "Lagrangian reduction" and "symplectic reduction". I guess you refer to non-holonomic constraints?
Thus even without constraints both formalism can be not equivalent, see Section 9. But as far as I understand, if we keep ourselves confined to systems with holonomic constraints only and whose Lagrangian function is "standard" or "regular" i. But in fact they are, for lots of systems of interest.
Note that, systems sattisfying the second of the above assumptions are sometimes called "mechanical" or "pure mechanical" systems in the literature. On the other hand, one does not have to go far in order to find systems violating one or both of the above assumptions: rolling without slipping is a common system with non-holonomic constraints and generally systems with resistance forces -various friction forces for example- violate the second of the above assumptions.
Note that Legendre's transformation, transforms functions on a vector space to functions on the dual space. In this case, it transforms the Lagrangian function on the tangent bundle of the configuration space manifold to the Hamiltonian function on the cotangent bundle of the configuration space manifold.
Such systems are more general than conservative systems and fall into the class of monogenic systems. With worked examples, 55 end of chapter exercises and chapter summaries The equivalence of various definitions of the canonical transformation is proved explicitly, in contrast to competing books Discussion of global symmetries and the Noether theorem in the framework of classical mechanics gives a new approach not covered by most mechanics textbooks see more benefits.

From the reviews: This handbook is well addressed to undergraduate students in physics. Hamiltonian Formalism Deriglazov, Alexei Pages Integral Invariants Deriglazov, Alexei Pages Show next xx.You can simply examine the oscillations around the equilibrium state by expanding the Hamiltonian to second order in the phase space variables.
In practise, the hamiltonian is frequently considered to be some abstract function while the Lagrangian is more intimately related to the concepts of kinetic and potential energy of some system. The road to quantisation through the hamiltonian formalism is generally refered to as canonical quantisation while the road through Lagrangian formalism is known as path integral quantization.
